I went to the ER a couple of days ago thinking I had a kidney stone. My back was killing me and I as vomiting. The kidney area was tender. After they determined that either there was no stone or it had passed they sent me home. I still cannot eat and I found a tender spot on my right front about 2 1/2 inches along the rib line from my sternum that has a little bump and if I press on it the pain goes all the way to my back where I first was experiencing severe pain symptoms. I still have no appetite although I am no longer vomiting. I drink water chamomile tea and have a piece of toast to eat. that is about it since Saturday at 1am. Any clue to what I am touching that is so painful all the way to my back. Is this a virus? or something else?
