Finger swelling and throbbing is a common complaint. There are a few causes that could implicated for your symptoms, some of which are minor and transient as well as some that are serious. I would recommend that you see your primary care doctor
in order to have this evaluated.
Your symptoms could be consistent with arthritis
. This is the inflammation of the joints -- and fingers are common joints that are involved. There are many causes of arthritis, but in your age group rheumatoid arthritis is a possible cause. This is inflammation in the joint caused by the immune system accidentally attacking the joints. Other related causes include lupus or psoriatic arthritis. Talk to you doctor about this.
Tendon inflammation can also cause these symptoms. This can be associated with overuse, and your keyboard use may be the culprit. This would require rest, reorganization of how you use your keyboard and often oral pills to reduce inflammation. Again, see your doctor to have this evaluated.
Finger swelling can also be caused by fluid retention. Kidney problems, heart problems and liver problems can also cause swelling. Pregnancy can also cause this.
Talk to your doctor. You may have any specific cause of your symptoms which need to be diagnosed and treated. Good luck!
