Reason for hard bump between knuckles on index finger?
Patient: Hard bump between the 2 knuckles on index finger. It appeared suddenly last week & not going away. No pain and I just worked the 24 Hours of Daytona-I joke about it being a muscle developed working so hard for a week without doing anything like that for a long time. Doctor: bump near the knuckles that is painless3 factors1)knuckles is near a joint its called mcp joint2)its painless3) and you have a history of strenuous activitypoints out to a ganglion cystits a non cancerous fluid filled mass occuring near joints after trauma or strenuous activityif its not painful treatment is just plain observationit usually resolves on its ownaspiration of the cyst can be an option but theres a 50% chance itll go back
