I Broke My Last 2 Fingers On My Left Hand.

I broke my last 2 fingers on my left hand. I was a fiberglass cast for 4 weeks went back said my fourth finger had healed. The pinky had not. He put me in a sling that had to be wrapped with stretchy elastic and had to wear it for 4 more weeks. Went back and he said it was well but I told him it still hurts and I can not find any kind of brace or stablizer to help me. I take Gabapentin 2 times 4 a day and also take Hydrocoldone if spelled correctly 1 to 2 times a day mostly at night so I can sleep. I am 75 year old.
