the surgeon removed the stent, and stone, and also his gallbladder, but he was in
a lot of pain
, and the op lasted for 4 hours. now, 4 weeks later he has a lot of pain in
his left shoulder, which his doctor has no idea what is causing it. we gather from your posts that this is probably trapped wind, but it has been 4 weeks since his operation. we wonder how long this will take to resolve itself, as we are getting no help elsewhere!
