I have started having tremors in my left hand recently and at times I have problems typing. It comes and goes but is starting to worry me. Has anyone experienced this? If so, have you had any success in treating it? I read online and most are not Parkinson's but something called Essential Tumors and the cause is not well understood. The medicines used have side effects and somewhat limited success. There is also a deep brain stimulator (used with Parkinson's) but they really don't want to use it until the tremors are really bad.
