The one thing I struggle with the most is knowing what is a flare up and what is a real relapse. I started feeling a numbness in my leg over a week ago but I’ve had this before so didn’t think much of it. I then started to get numbness in my left hand up my arm and my shoulder is so sensitive to touch and itchy! Again, I have had a little bit of numbness in fingers before but not up my arm? I find it so difficult to know what’s new and what’s old when it comes to symptoms!! I just don’t know if I should contact my nurses because even if it was a relapse there is not really anything they can do??
