Can something else be going on?

I am banded 3 yrs now . 6 days ago I had a severe case of a stomach virus , vomiting, diarrhea, nausea,I lost 11 lbs in 2 day. I decided to go to er and they did a cat scan and gave me medication for nausea..Dr came back with results of no slippage but lots of imflammation around the band which he suggested I see a specialist the next morning unfortunately I was still to very sick to go . now 6 days out and I feel nausea again and pain on left side. can something else be going on
