I've also lost fine motor control and can no longer do things like write. One of the drugs they put me on gave me tremors that have not gone away so now I can no longer write or use a soldering iron. Sometimes tremors are bad enough typing is literally hit or miss. I miss juggling and cartooning.
For the first 10 years I chased doctor after doctor hand surgeon orthopedic surgeon etc. looking for a cure. Nobody gave me consistent diagnosis and even some of the recommended surgical interventions for some of my symptoms were not recommended because I didn't present in a way that indicated the surgery would be successful.
I've tried numerous things acupuncture, physical therapy, trigger point massage, and drugs like gabapentin and tricyclic antidepressants. The only thing that gave me any relief whatsoever was lidocaine injections in trigger points around my shoulders. The release lasted only 48 hours but it was so wonderful.
I've given up that there's any medical intervention that will help and I just have to live with it the rest of my life.
