After I had my son, when picking him up for feedings, etc, I seemed to have sprained my knuckle on my dominate hand / right hand first finger to r of thumb. My son is now 3 yrs old, and it feels as if it has never healed. Can't remember a time after my sons birth where I did not have this problem. for the last 6 mths or so, it has become a terrible burning sensation whenever i brush my knuckle into something, or need to open a jar or soda. I have taped my first 2 fingers together, to try and stabilize the digit. When it was not taped up I found it difficult to make it through an hr or so with out it becoming overbearing pain. Any use of the finger brings on intense burning in the knuckle. What have I done and how do I relieve the pain?
