I also had a cyst removed 5 weeks ago and am experiencing severe abdominal cramping along with a pain that travels down to my crotch. I just had an ultra sound yesterday to see if I had done something during recovery. She spent alot of time taking pictures of the uterus and stuff. I had gone to emerg on Monday and the dr. said I was constipated which I was, but I know there is more to the pain.
Endometriosis can also cause abdominal cramping... what kind of cyst did you have?
I have a 5cm hemorrhagic cyst on my left ovary. I cannot sleep on my left side and sitting is uncomfortable like a pain under my left rib cage. I have extreme gas and feel sick to my stomach in the morning like a terrible hunger pain. It definitely has something to do with the cyst and ovary. My gyno told me it wasn't big enough to be causing this kind of pain but I have been in this kind of pain since last February.
I think you should schedule a check-up to the same doctor that have done your surgery. I'm sure he/she have a better explanation on it. I'm a bit sure that it was really the side effect of the surgery.
