I am 10 days out from my revision from sleeve surgery to RNY. I was doing wonderful until yesterday when I now have lower back, right sided pain with every breath I take. I was doing my incentive spirometry (breathing apparatus) and was up to 2000 (baseline) until yesterday. With this sharp pain I can only get to 750. I am passing lots of gas :), but that is not relieving this pain. I have transitioned a few days ago to full liquids. My surgeon is very conservative on advancing diet. Any thoughts? Good news is I am down 17 lbs. in 10 days.
