I have numbness in my right thumb and index finger. My hand feels swollen, though it is not. Vague numbness in forearm as well. Involuntary movement in thumb, where it pulls involuntarily into my palm, and I have severely reduced coordination in my right hand. As an MS patient, I was treated with Solumedrol 2 weeks ago, with no improvement, in fact seemingly worse symptoms now. Is there anything else this could be other than an exacerbation?
