What other symptoms are you having? Pain, nausea, any fever, diarrhea or constipation?
I have never heard of a "collapsed" GB. But if you have spasms of the GB that could be due to stones or sludging of bile in the GB. Depending on the cause I think there are a few treatments. Most doctors especially surgeons would suggest removal. Since I have had mine removed and haven't felt great - I would try to avoid surgery if I could.
