Starting this week I have been getting a crampy feeling in the bottom of my foot. Its right in front of where the heel of my foot is and it goes from side to side. I have a bulging disc on my S1 nerve root and have had sciatica, and ever since I had an ESI a month ago new symptoms keep popping up. I was just wondering if this feeling in my foot is related to the sciatica. Anyone else have this?
