On May 13, 2015 I had a cholecystectomy (removal of my gallbladder) and everything went well until last night. It still feels like one of the clamps they put in after they did the operation is either stabbing something or it came loose or off. It is sore and hurts right in my stomach area and right under my the last rib on my right side of my ribcage. I didn't sleep at all and now it is sore right in the area of my appendix. I was throwing up last night by the way. What should I do? My sister (whos 36 years old, and I'm only 16 by the way says the clamp is just fine but it doesn't feel like it.
