I've been experiencing pain in my lower left side of ab and lower back pain. They feel more like muscle aches. This has been going on for about two yrs but has gotten progressively worse this summer. I've had ovarian cysts and surgery for the cysts in 04,05. After my laposcopic surgery in 05 I noticed that my weight has gone up. I'm anorexic but it seems even if I restrict everything my weight has continued to go up. I mostly restrict and purge. From sept 05 to now my weight has gone from 105-120. This is really hard to take because I haven't kept any meals down in yrs. I went to my gyno dr and she cleared me of cysts. The gastro doc diagnosed severe gastric reflux, ulcer, and gastric emptying sydrome. I don't get this unexplained weight gain. From what I read all these conditions are most likely to make you lose weight. Why the gain? Help!!!
