Hi, numbness was actually my first main symptom. It started in my right foot and worked its way all the way up my leg to just below my lower shoulder blade. My arm seems to be fine but everywhere else I am numb on the right that my body, as if you drew a line straight down the center. I would compare my numbness to a trip to the dentist, you know how when they shoot you up with Novocain you're lip feels all funny? Like you can touch it and you can tell you're touching it but you could bite it, make it bleed, and not even know.
That's how my numbness feels, if I put my hands on my leg I know I'm touching my leg however, I could easily grab a razor blade right now and cut into my leg and not even feel it. The way I feel temperature has also changed on the right side of my body where I am numb. Cold burns! When cold water splashes on me it feels like hot oil popping on my skin from a frying pan! I don't really seem to feel heat considering I first realized I was numb when I learned I could keep my foot under the scolding hot faucet water in my bathtub as long as I wanted to even though just tapping my other foot under the water for just a split second burnt! It also hurts to touch anything else cold such as a cold piece metal or even a cold table surface(my right arm gets a little sensitive to cold sometimes even though it's not numb), really weird...
I am just glad that it stopped at my shoulder blade and didn't make its way to my face or my arm... I was scared at first, but I have to admit, since my other symptoms popped up I hardly even think about my numbness, I guess because I still have SOME feeling it doesn't get in the way too much... Just have to be careful that I'm not burning my skin or anything like that.
But it's really good that you are started steroids, that does wonders for people! It's definitely helped me improve, but I still have my numbness... I start my injections this week and will be starting an anti-inflammatory diet pretty soon so I'm hoping between that and my oral steroids that I will go into remission soon, but in your case, I wouldn't worry too much, the steroids will probably help but keep in mind you might see effects as soon as three treatments or as long as two months, fingers crossed! Good luck!
