My weakness is on my right side, ie walking and right hand holding/writing. However, for the last three weeks or so, I’ve been having a constant stinging or burning sensation above/on my left knee. I keep checking it to see if there is a redness or a rash. (There isn’t) There is nothing to see, nothing. It’s not painful or itchy but it feels like a nettle sting, or sunburn. Driving me nuts now. Is this anything to do with MS or has anyone any ideas? I will feel foolish mentioning it to my Neuro when I see her next week if it’s irrelevant.
