Gallbladder removed 4 months ago woke up with severe pain on upper right side. i feel as if i am having another gallbladder attack, is this common?

See MD ASAP: This could represent a retained stone in your common bile duct... In general terms please note that severe pain suggest urgent medical attention, not a web site...

Bile duct stone?: There are a number of tests, ultrasound, mrcp that you could have to rule out a retained or new primary gallstone in your bile ducts. If these are clear an EGD/ERCP may help. IF negative you may need additional testing. If it is not a stone then review your meds. Many things can cause right sided pain. See a surgeon or GI doc
