I just found this forum tonight and I am hoping that it is the answer to many problems that I've had lately. I seem to have many symptoms described by others here, but I am particularly interested in the weird sensations that you feel in your left arm and leg. I've had some weird sensations too and I'm not sure how to describe them. It is like a mild vibrating sensation or maybe I would describe it almost like a buzzing sensation. I'm not sure if that make sense. It sort of comes and goes. Mine are on my left side too. I've noticed a lot of people have reported problems on their left side. Weird.
