Few years ago I had RnY surgery...things were great at first, I lost 120#...now I've been treated for severe anemia (IV therapy) and hystrectomy (healthy uterus)...but I had to go to the ER twice in the last 2 weeks due to severe left side belly pain...my stomach constantly "rumbles"' with constant back pain, and I just don't feel like eating...the pain was so severe I went into shock, and hyperventalated...but all my doc would say was it's "just muscle spasms", but this is one time I feel the doc isn't right...any opinions?
