I'm going to see my neuro this week and will ask him but wanted to ask the experts -- all of you! -- if you have any idea if this is an MS thing. I have been having cramping in the arch of my feet especially at night. I was dx'd with bursitis in my feet and after I finally started to get relief from that by taking my extra strong anti-inflamatory meds this cramping started. I started taking potassium and it seemed to help for a while but now the cramping is back. I know it's a small thing, it could be so much worse, and I hate to whine about but ignoring it doesn't seem to be helping this time. Anyone have any ideas or suggestions??
