Hello,
I have this numbness too, but the numbness is in my arms, and hands. Just holding the steering wheel to drive causes my hand to get numb.
I am very sun sensitive, and could not even dream of hiking in the sun. Sure wish I could. Just two days of picking up my grandchildren from school, caused me to be sick the rest of the day. drained of energy, weak, dizziness sometimes when I stand up. Luckily it is mostly gone after a good night's rest.
It seems to me, but could just be me looking for stuff, but it seems to be worse when the sun is high in the sky, and I don't seem to be as sun sensitive in the winter time as I am in the summer.
since this numbness has been talked about here, I will mention it to my rheumy. I have been listing evey single thing that I think is important to take to him the next time I see him. Didn't know if the numbness was important, or if it was due to me doing something that normal people would also have the circulation cut off.
thanks
