Tennis elbow, also known as lateral epicondylitis, is a condition in which the outer part of the elbow becomes painful and tender. The pain may also extend into the back of the forearm and grip strenght may be weak. Onset of symptoms is generally gradual. golfer’s elbow is a similar condition that affects inside the elbow.
Tennis elbow, or lateral epicondylitis, is a painful condition of the elbow caused by overuse. Not surprisingly, playing tennis or other racquet sports can cause this condition. However, several other sports and activities can also put you at risk.
Tennis elbow is an inflammation of the tendons that join the forearm muscles on the outside of the elbow. The forearm muscles and tendons become damaged from overuse — repeating the same motions again and again. This leads to pain and tenderness on the outside of the elbow.
There are many treatment options for tennis elbow. In most cases, treatment involves a team approach. Primary doctors, physical therapists, and, in some cases, surgeons work together to provide the most effective care.
Anatomy
Your elbow joint is a joint made up of three bones: your upper arm bone (humerus) and the two bones in your forearm (radius and ulna). There are bony bumps at the bottom of the humerus called epicondyles. The bony bump on the outside (lateral side) of the elbow is called the lateral epicondyle.
Muscles, ligaments, and tendons hold the elbow joint together.
Lateral epicondylitis, or tennis elbow, involves the muscles and tendons of your forearm. Your forearm muscles extend your wrist and fingers. Your forearm tendons — often called extensors — attach the muscles to bone. They attach on the lateral epicondyle. The tendon usually involved in tennis elbow is called the Extensor Carpi Radialis Brevis (ECRB).
Symptoms
The symptoms of tennis elbow develop gradually. In most cases, the pain begins as mild and slowly worsens over weeks and months. There is usually no specific injury associated with the start of symptoms.
Common signs and symptoms of tennis elbow include:
- Pain or burning on the outer part of your elbow
- Weak grip strength
The symptoms are often worsened with forearm activity, such as holding a racquet, turning a wrench, or shaking hands. Your dominant arm is most often affected; however both arms can be affected.
Cause
Overuse

Recent studies show that tennis elbow is often due to damage to a specific forearm muscle. The extensor carpi radialis brevis (ECRB) muscle helps stabilize the wrist when the elbow is straight. This occurs during a tennis groundstroke, for example. When the ECRB is weakened from overuse, microscopic tears form in the tendon where it attaches to the lateral epicondyle. This leads to inflammation and pain.
The ECRB may also be at increased risk for damage because of its position. As the elbow bends and straightens, the muscle rubs against bony bumps. This can cause gradual wear and tear of the muscle over time.
Activities
Athletes are not the only people who get tennis elbow. Many people with tennis elbow participate in work or recreational activities that require repetitive and vigorous use of the forearm muscle.
Painters, plumbers, and carpenters are particularly prone to developing tennis elbow. Studies have shown that auto workers, cooks, and even butchers get tennis elbow more often than the rest of the population. It is thought that the repetition and weight lifting required in these occupations leads to injury.
Age
Most people who get tennis elbow are between the ages of 30 and 50, although anyone can get tennis elbow if they have the risk factors. In racquet sports like tennis, improper stroke technique and improper equipment may be risk factors.
Unknown
Lateral epicondylitis can occur without any recognized repetitive injury. This occurence is called “insidious” or of an unknown cause.
Tests
Your doctor may recommend additional tests to rule out other causes of your problem.
- X-rays. These tests provide clear images of dense structures like bone. They may be taken to rule out arthritis of the elbow.
- Magnetic resonance imaging (MRI) scan. If your doctor thinks your symptoms are related to a neck problem, an MRI scan may be ordered. MRIs scans show details of soft tissues, and will help your doctor see if you have a possible herniated disk or arthritis in your neck. Both of these conditions often produce arm pain.
- Electromyography (EMG). Your doctor may order an EMG to rule out nerve compression. Many nerves travel around the elbow, and the symptoms of nerve compression are similar to those of tennis elbow.
treatment-
f simple treatments can help alleviate the pain of tennis elbow. The most important thing you can do is rest your injured arm and stop doing the activity that caused the problem (see below).
Holding a cold compress, such as a bag of frozen peas wrapped in a towel, against your elbow for a few minutes several times a day can help ease the pain.
Invasive treatments, such as surgery, will usually only be considered in severe and persistent cases of tennis elbow, where non-surgical approaches have not been effective.
Avoiding or modifying activities
If you have tennis elbow, you should stop doing activities that strain affected muscles and tendons.
If you use your arms at work to carry out manual tasks, such as lifting, you may need to avoid these activities until the pain in your arm improves.
Alternatively, you may be able to modify the way you perform these types of movements so they do not place strain on your arm.
Talk to your employer about avoiding or modifying activities that could aggravate your arm and make the pain worse.
Painkillers and NSAIDs
Taking painkillers, such as paracetamol, and non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, may help ease mild pain and inflammation caused by tennis elbow.
As well as tablets, NSAIDs are also available as creams and gels (topical NSAIDs). They are applied directly to a specific area of your body, such as your elbow and forearm.
Topical NSAIDs are often recommended for musculoskeletal conditions, such as tennis elbow, rather than anti-inflammatory tablets. This is because they can reduce inflammation and pain without causing side effects, such as nausea and diarrhoea.
Some NSAIDs are available over the counter without a prescription, while others are only available on prescription. Your GP or pharmacist will be able to recommend a suitable NSAID.

Physiotherapy
Your GP may refer you to a physiotherapist if your tennis elbow is causing more severe or persistent pain. Physiotherapists are healthcare professionals who use a variety of methods to restore movement to injured areas of the body.
Your physiotherapist may use manual therapy techniques, such as massage and manipulation, to relieve pain and stiffness, and encourage blood flow to your arm. They can also show you exercises you can do to keep your arm mobile and strengthen your forearm muscles.
The use of an orthoses – such as a brace, strapping, support bandage or splint – may also be recommended in the short term.

Steroid injections
Steroids are a type of medication that contain manmade versions of the hormone cortisol, and are sometimes used to treat particularly painful musculoskeletal problems.
Some people with tennis elbow may be offered steroid injections when other treatments haven’t worked.
The injection will be made directly into the painful area around your elbow. You may be given a local anaesthetic first to numb the area and reduce the pain.
Steroid injections are only likely to provide short-term relief and their long-term effectiveness has been shown to be poor. If they are helping, you may be offered up to 3 injections in the same area, with at least a 3 to 6 month gap between them.
Shockwave therapy
Shockwave therapy is a non-invasive treatment, where high-energy shockwaves are passed through the skin to help relieve pain and promote movement in the affected area.
How many sessions you will need depends on the severity of your pain. You may have a local anaesthetic to reduce any pain or discomfort during the procedure.
The National Institute for Health and Care Excellence (NICE) states that shockwave therapy is safe, although it can cause minor side effects, including bruising and reddening of skin in the area being treated.
Research shows that shockwave therapy can help improve the pain of tennis elbow in some cases. However, it may not work in all cases, and further research is needed.
PRP injections
Platelet rich plasma (PRP) is a newer treatment that may be offered by a surgeon in hospital to treat tennis elbow.
PRP is blood plasma containing concentrated platelets that your body uses to repair damaged tissue. Injections of PRP have been shown to speed up the healing process in some people but their long-term effectiveness is not yet known.
The surgeon will take a blood sample from you and place it in a machine. This separates the healing platelets so they can be taken from the blood sample and injected into the affected joints. The procedure usually takes about 15 minutes.
Surgery
Surgery may be recommended as a last resort treatment in cases where tennis elbow is causing severe and persistent pain. The damaged part of the tendon will be removed to relieve the painful symptoms.
