Am I a wls failure?

you should go to the doc.  You are not a failure.  In future if you need the NSAIDS go for the childrens liquid.  I was in a car accident and injured both knees my back and neck.   I was put on celebrex which damaged my kidneys and I gained 60 pounds.  The I had kidney failure and diaylsis when I got tennis elbow (don't ask me how I don't play tennis) they put me childrens liquid and orderd blood work every week to see wha it was doing to my kidneys.  I can't have NSAIDS without the risk of kidney failure.  MAybe Dr. shina could do a revision.  JUst put your chin up and know you are doing your best.  But get that stomach looked at asap.
