Yep - I had a bout of TMS induced Sciatica that lasted for about 45 days last year. It was my first TMS issue coming on the tail end of some other stress in my life. Very sore left leg up in to my lower left back, butt, calf and foot. Tingling, pain, cramping calf, electric jolts.
MRI showed a slight pinched nerve on the other side of my body....which was comical. Doctor just said it was sciatica and would go away one day most likely so I started running again. After about day 3 the pain started to go away and was gone within a week. Still today it pops up a little but I just ignore it 100% now and it fades away.
