I've picked up what I initially thought was a cold about 4 weeks ago. The normal cold symptoms lasted for about a week. Then eased up for a week. But then came back in full force once again. I'm finally starting to feel a better now but its flared up a number of my MS symptoms. My left arm was always slightly purple. But its a really dark red/purple now, same with my left foot. I also now know what everyone means by cold feet. It was never cold feeling before, but now its a is so cold feeling its painful.
I find it odd that all thats flared up is the symptoms that seem to be due to circulation.
