Sounds like your gallbladder. I had mine out a few years ago. I suffered for years with on and off pain like yours. I had all the usual tests and everything came back normal. Finally I heard about the Hida test. It confirmed that my gallbladder wasn't working properly. After I had the surgery to remove it, I've been pain free.
Isn't it awful how long we have to wait for these test? I had to wait 6 weeks for a colonoscopy and endoscopy. They did that to rule out other things. I live in NY State and they have closed quite a few hospitals around my area, so the wait is getting worse for everyone.
Same problem here. Everything came back normal. HIDA scan booked for Sept. 4.
I have the same symptoms, sounds like your gallbladder. I have had the ct-scan and ultrasound. All normal. Now I am having a Hida Scan on the 18th. All other test can come back normal and it can still be your gallbladder. I would ask for a hida scan. I will let you know how I make out with mine.
