I just found this site today. I couldn't believe my chronic upper back & lower neck pain could be related to my gall & reflux problems. I'm 25 & had x-rays done that the doctor suggested could be arthritis. I just had ultrasounds of stomach areas & upper GI. I have reflux & am being put on a med for that. During my ultrasound my liver, stomach, etc. were all seen clearly and empty, but my gallbladder was black. I didn't eat or drink 12 hrs before tests. I am now being sent for a Hida scan-although I don't know what that is-because they said something is there but they don't know what. Could anybody give me possibilities of what is going on? Will I possibly need surgery? Thank you for your info.
