This thread is a few months old so I didn't know whether I should start a new one.
I'm having this same symptom, buzzing in my lower bowel. It only occurs a few times a day for about 10 seconds. It just started a few days ago and I'm also feeling like something is moving or crawling in my feet. I've never had such a weird thing ever. How do you get rid of this? Where did it come from? Is it serious? It's creeping me out.
