So I've been rolling for about 2 months, I did it about 4-5 times total. 3 days ago I rolled for the 4th or 5th time. Starting about yesterday, I started having these wierd "bursts" or "rushes" that would almost feel like a buzzing sensation in my nerves and it would feel like a "rush" in my head. They happen rather frequently, but they seem to happen at certain times of the day. They aren't that intense, but they are annoying. Has this happened to anyone else? Does it go away in time?
