It feels hard like a bone in itself, unable to be massaged away. When I play, it becomes distinct, and usually there is some dull pain, sometimes a feeling of weakness. Thanks for your advice. This is a benign problem and responds to deep tissue massage techniques and other natural therapies. Of course, you would need to be examined to determine the exact nature of the problem.
Ganglions develop due to a prolonged stress on the tendon.
I would take a look at your playing style to see if you are stressing your hands in any way. You always have to look at the underlying stressors to determine why the problem is developing. If you don't, you'll simply run the chance of redeveloping the problem again. I would recommend a hand x-ray to rule out any oddball things that could be causing this bump. I would implement massage therapy in with the chiropractic care to help the tendons heal properly.
