What exactly does a spasm feel like and does anybody know if it is possible to have an AF without experiencing spasms. I'm sure I have an AF but I'm not sure I've experienced spasms. I get the pain during/after a BM and I've been jumping straight in a hot bath, that mostly sorts me out, other than an annoying nagging pain that may or may not last for a bit, but it doesn't feel like what I'd imagine a spasm to feel like, it's more of a stinging pain or a dull ache, but not excruciating, so I'm wondering can you have an AF but not get the spasms?
