Hi,
You mentioned burning. I think your burning is from your surgery. Pulling, pinching, or cut stomach muscles perhaps. I had a hysterectomy 15 yrs. ago and from time to time get extreme burning pain when I move the wrong way or too quickly. I got a cold right after going home from the hospital and a sudden sneeze caused me to move suddenly and pull & tear on the inside of my incision.Sitting around won't help tighten those muscles either.Strenghtening them might help some.
I also had MRSA last year but it started as a pimple/boil under my arm. I have no idea where I got it and am not yet fully recovered. Mine went from removal of a boil under my arm to pneumonia, then to the hospital & nearly dying all in a matter of 10 days.They tried several antibiotics until they found ones that worked. All kinds of different symptoms are still going on. Alot of skin irritations and rashes. And now I have asthma. Sometimes I wonder if some of the symptoms aren't caused by some of the meds they pumped into me. I am hoping to some day be back to normal. As for you, I don't think your ordeal is over yet either. It sounds like you need more medical attention.
