Finger pain has many possible causes. The most common are accidental injuries, overuse injuries, and arthritis. However, numerous hand-related and body-wide health conditions can lead to finger pain, including Dupuytren’s contracture, trigger finger, ganglion cysts, infections, autoimmune diseases, and peripheral neuropathy.
Rheumatoid arthritis (RA) is known for causing all-over inflammation and pain. It happens when the immune system malfunctions and attacks the synovium, the lining of the joints. RA can target the synovial lining of the shoulder joint.
Dupuytren's contracture is a condition that causes tight tissue to form in the palm of the hand and fingers. Exactly why this condition occurs is a bit of a mystery, but there is a known genetic component and there have been other factors including lifestyle, activities, and other medical conditions that may also play a part.
Armpit pain can have many causes, ranging from injuries and irritants to infections that cause swollen lymph nodes. Less commonly, the pain—referred to as axillary pain—may be due to an autoimmune or arterial disease, nerve compression, and malignancies like breast cancer.
Extensor tendonitis is an inflammatory condition of the tendons on the back of the hands or the top of the feet. These tendons attach to muscles that straighten your fingers and lift up your toes and the top of your foot.
