I would suggest seeing your
doctor. 1 month is a long time to have this kind of pain, and it is worth getting it checked out to see what is going on.
One possibility that is highly likely is that you have tendonitis of the elbow. When the tendons of the elbow are inflamed, this can lead to quite severe shooting pains, especially with exercise or heavy work, and some problems with weak grip in the hands. When the tendons that are inflamed are on the outside of the elbow, this is called tennis elbow, or lateral epicondylitis. When the tendons that are inflamed are on the inside of the elbow, this is called golfer's elbow, or medial epicondylitis.
The treatment for either form of epicondylitis involves resting from the types of sports and other physical activity that provoke the discomfort. In addition to rest, anti inflammatory medications like ibuprofen or naprosyn can be very helpful. In more advanced cases, physical therapy and braces can also be helpful, as can certain stretching exercises.
Your
primary care doctor or a
sports medicine doctor will be able to help you figure out what is going on and give you some advice about what you should do.
