I haven't had what you are talking about but if your doctor is right can you see a neurologist? I have a neurological tremor, it effects my fine motor skills when it is active. My primary care doctor knew what it was but was not up on the latest research. I went to a neurologist and when it was active was able to take anti-seizure drugs because they somehow work on it. It is also one they don't know the cause (believe it is a gene I have possibly) but do have some relief. Good luck, neurological issues are one of medicines obnoxious guessing games but I bet relief can be found. (((HUGS)))
