Hello, I have been getting this strange sensation that someone is holding a cold cloth on my lower back. It comes and goes and it's happened before but that was a few years ago. Lasted a month or so then and it's been a week or so now. I've never had any back injuries and don't have any chronic illnesses. I have had 2 epidurals and 2 spinals in my lifetime. I'm not sure if it could be related. I have read some info on MS causing these types of symptoms. Any thoughts?
