After my surgery last year in June, I felt great, but I had a really bad relapse in November, with vomiting and stuff, then again in December, then in January. I went to the doc in December because I suspected restenosis, but it was nothing of the kind. Since January I have had one more relapse with tingling. The thing is that apart from the relapse in November, all the other relapses were king of mild, I wasn't in bed, I actually didn't tell anyone

) I was just feeling stiff in my left side of the body and dealt with it with baclofen. Relapses are getting milder and milder (may this trend continue, I pray!), so if it is not re-stenoses, maybe you just have to wait. But you should definitely check out for re-stenosis.
All the best...
