Hi, I know pins and needles are normal in MS. Recently though I have been getting it worse when sitting, especially when I am sitting slightly to the side, sometimes even a smidgen. It happens minutes after sitting and turns into numbness very quickly. I have to move my leg around before I walk as I can’t feel much of my left leg. The left sided pins and needles started 10 years ago so it’s not new to me, just the sudden decrease in feeling. Thankfully it goes back to my normal (numbness and pins and needles in left foot) after about 20 mins.
