<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi. I had a colonoscopy about 12 hours ago. About 3 hours ago I noticed a sharp pain in my left shoulderkind of feels like a pulled muscle I read that it could be a sign of ruptured spleen but I don t really have other symptoms. Should I be worried or is this normal?  <response>: Hi.if you have a ruptured spleen, you wouldnt be able to have the time to spend here as its symptoms are usually acute in character. Usually, a severe abdominal pain, flank discoloration, decreasing blood count and probably other constitutional symptoms like fever. What youre experiencing right now might be a muscle strain or positional. If its persistent and progressive, a follow-up with your doctor would be best. Abdominal CT-scan could easily rule-out if you have a ruptured spleen. Hope this helps. Good day!! Chat Doctor.
