I've had a week where I didn't have a panic attack but Thurs I had one. I've had a really bad week with things goin on where u would think id have suffered a panic attack then but I didn't. Tues I had bad belly cramps due to my ibs and its still a bit iffy today. Any way I had a really weird sensation in my chest n then my right arm twitched. I can't explain how it felt in words. Is this normal with anxiety as I don't think I've had that feeling before.
