Trigger finger, also known as stenosing tenovaginitis, is a common condition. It usually affects middle-aged patients, especially manual workers required to frequently flex and extend their fingers. These repeated finger movements cause wear and tear to the finger tendons and result in inflammation, which eventually leads to tendonitis (tendon swelling and thickening). The swollen or thickened tendon can become trapped at the entrance to the tendon sheath -the fibrous tunnel that holds the finger tendon in position - and produces the triggering effect when the finger tendon is forcefully moved through the tunnel then releases. Any finger can be affected, but the thumb and fourth fingers are most affected. You may notice that the finger clicks as it is bent, then when the hand is extended, the affected finger remains bent until it suddenly straightens with a snap. Sometimes, a lump (nodule) will be formed, and it can be felt along the tendon. As the condition worsens, the affected finger may be trapped in the palm of the hand and can only be manually extended with the other hand. In the worst scenario, the flexed finger is completely trapped and cannot be manually released.

Trigeminal neuralgia is a chronic pain condition affecting the trigeminal nerve in the face. This nerve is responsible for sending sensation impulses from the face, teeth and mouth to the brain. When it becomes irritated or inflamed, it can send sharp, painful impulses to one side of the face. These typically last between seconds and minutes. Symptoms can be triggered by very light touches to your face, such as brushing your teeth or chewing. A flare-up of trigeminal neuralgia usually lasts several days or weeks to months, and then you may recover. It may settle for good, or it may come back months or even years later. Compression of the trigeminal nerve causes these symptoms and is commonly due to a blood vessel impinging on the nerve. Much less commonly, it can be caused by a tumour or associated with other neurological conditions like multiple sclerosis. Trigeminal neuralgia is uncommon - About 1 person in 10,000 develops it each year. It mainly affects older people, and it usually starts in your 60s or 70s, but is rare in younger people. Women are more commonly affected than men.

A tension headache is the most common type of headache and feels like a tight band has been wrapped around your forehead, causing a constant ache to the sides of the head. Your neck or shoulders might feel tight and tender and a dull ache or pressure can build up behind the eyes. It’s commonly referred to as a stress headache for good reason – it comes at the busiest or most stressful times. While frustrating, for most people it’s mild enough for them to be able to continue with everyday activities. In medical terms, it’s known as a primary headache which – put simply – means that there is no underlying medical condition causing it. It may last between 30 minutes and a few hours. More rarely, some people get a chronic tension-type headache that can last for much longer, or come and go for days within a flare-up period. Most describe tension headaches as mild and short-lived. Many feel better after a sleep or a warm bath, and tension headaches usually respond well to simple painkillers. Let's talk you through how to shake off a tension headache and how to avoid triggers in future.

The term ‘tennis elbow’ is more correctly known as lateral epicondylitis and is a painful condition affecting the outside part of the elbow. The lateral epicondyle is the bony prominence at the outer part of base of the humerus or upper arm bone. A similar condition affects the medial epicondyle (the bony prominence at the inner part of the elbow) and is usually called 'golfer's elbow'. What causes tennis elbow? This is all because of our anatomy. The muscles that straighten out our wrist and fingers anchor onto a small bone at the outer side of the elbow. Repetitive movement under tension of these muscles can irritate the sheath these muscles are contained within and also cause tiny tears of the muscle too. The subsequent irritation and inflammation then causes all the symptoms and these symptoms are probably related to the poor healing process rather than to any original injury. Who gets tennis and golfer's elbow? Any sport, hobby or work activity in which repetitive arm movement, a type of RSI and muscle overstraining are involved can cause it, with the highest risk involving using a bent elbow while holding a racquet or tool. It also affects people more frequently over the age of 35 and both men and women are affected equally. It is uncommon in people under 30, probably because the healing ability of the tissues is better below that age. How do I know I have tennis elbow? It usually starts with discomfort on the outer part of the elbow that gradually increases with movement. Pressing on this part is painful as is bending the wrist upwards against pressure. The wrist may feel weak so picking up everyday objects such as books or pans may become difficult. Eventually, the pain travels all along the upper arm and outer part of the forearm and it may get so painful that the arm is held close to the body to prevent it hurting. There is usually tenderness over the lateral epicondyle in tennis elbow, and over the medial epicondyle in golfer's elbow.

Tendonitis is a common painful condition that can affect tendons around a joint. In most cases, tendonitis is a self-limiting condition and will improve after a period of activity limitation. Tendonitis was previously believed to be a condition of inflammation within a tendon. However, it is now understood that tendonitis does not involve inflammation and instead represents multiple micro-tears accumulating and the tendon generating a healing response. Most cases of tendonitis are caused by a sudden change or increase in your activity levels.

Subacromial impingement (also known as shoulder impingement syndrome) is a condition characterised by painful movement of the shoulder. Pain often occurs when moving the shoulder and arm in specific directions and can be associated with weakness. Subacromial impingement is one of the most common causes of shoulder pain. It most commonly affects people aged 30-70 and around one in five people will experience symptoms of subacromial impingement at some time in their lives. Subacromial impingement tends to cause pain that can be felt at the top of the shoulder and can spread down the arm towards the elbow, pain worse when lifting your arm to side and above your head, weakness when lifting your arm to the side.

Septic arthritis is an infection in a joint that always needs to be identified and treated as soon as possible to avoid irreversible joint damage and further risk to your health from sepsis. If you are concerned you have septic arthritis you should seek urgent medical attention. Septic arthritis is a significant problem, but if treated early and the infection is cleared, you should be able to avoid any long-term problems to the joint or to your general health. Many different infections can cause septic arthritis, but the most common is Staphylococcus aureus. Although anyone can develop septic arthritis at any age, it is most common in very young children.

Sciatica is a broad term used to describe symptoms caused by compression or irritation of the sciatic nerve or its contributing nerve branches. The sciatic nerve is the largest nerve present at the back of the leg - it passes the lower back, down the hamstrings and the outside of the lower leg to the foot. It controls the muscles at the back of the thigh, all muscles below the knee and it provides sensation to the skin of most of the leg. Sciatica is characterised by a sensation of pain, tingling, or burning passing along the course of the nerve, extending from the lower back down into the leg. The specific location of the pain or altered sensation is dependent upon the nerves that are irritated or compressed. Sciatica is often associated with low back pain. The most common cause of sciatica is from a prolapsed intervertebral disc. Here a part of the fluid-filled centre of the intervertebral discs (the discs which separate each of the spinal column bones) is allowed to leak out through a tear in the outer disc layer. This prolapse, or disc bulge, causes direct compression or irritation of a nerve which causes the symptoms of sciatica.

A rotator cuff tear refers to a tear of one of the tendons of the rotator cuff. The rotator cuff tendons of the shoulder are a set of tendons responsible for the movement of the shoulder in different directions. A rotator cuff tear is a common cause of shoulder pain and is typically associated with weakness in certain shoulder movements. Rotator cuff tears are a common cause of shoulder pain and become more common with increasing age. Rotator cuff tears in younger people are most likely the result of a specific injury, whereas rotator cuff tears in older people are typically the result of longstanding tendon degeneration.

Restless legs syndrome (RLS) is where you get an irresistible urge to move the legs that is difficult to overcome. It can affect women twice as commonly as men but can affect any person at any age although it tends to be more common the older you are. It is surprisingly common with some estimates suggesting that up to 1 in 20 of the population can be affected at some time.

Repetitive strain injury (RSI) is very common and is when repetitive movement causes pain due to overuse or strain of muscles, ligaments, or tendons. The symptoms can range from pain and aching to numbness or tingling and they tend to start and are made worse by doing repetitive movement. It can occur in the areas around different joints or muscles in the body switch the most common areas being the hands, wrists, forearms, shoulders, and neck. Along with repetitive movements, stress, vibrating work tools, and cold weather can also increase your risk of developing RSI. Common reasons for developing RSI are doing repetitive tasks at work, using a computer or mouse, gaming, sportspeople, wheelchair users, and musicians. However, not everyone in these categories develops RSI.

Reactive arthritis is a reaction that occurs in your body, usually after you’ve had some sort of infection. It causes an arthritis-type response in your joints with symptoms of swelling, redness, and inflammation. Commonly, it affects the joints of the lower legs, including the knees and hips, but it can also affect any joint. In the majority of cases, there are no long-term complications, although it can take a few months to clear up properly.
