Not after ccsvi treatment (next month, can't wait) but after IBT! Three times: when I first started it, when I bumped it up higher, and when I came back after two weeks vacation. Tingling buzzy feet but in a good way. Not sure if this helps but I wanted to post because it was something I was not expecting and I have to assume it's a blood flow benefit from the IBT; I can't say I understand it. Each time it only lasted a few days.
