Im pretty sure it hasnt actually popped, but somethings not right...But, Can clamps pop a fistula? or dislodge a stent? Or something like that?? I never use the clamps, but I was really out of it yesterday, so they decided it would be best... When she applied the second clamp, i felt pain around the area that my stent was placed,(up near my shoulder/chest area.) when the clamp was removed though the pain went eased for a little bit. Last night, after Id taken my nap when I got home, I was in pain there full force again, and it hasnt eased since. Whats really strange, if I take a deep breath, it is even more painful. I dont really want to do ER (its sunday...) so I am wondering if it can wait? If I should be concerned? There doesnt seem to be any noticeable bruising. Just hurts.
