I have burning and a gnawing sensation on the left side right below the ribs as soon as I swallow food. It is like I can feel it as soon as my food reaches that area. Usually goes away in a few seconds until the next bite. Went to the doctor and she is unsure. She is going to do some blood tests to try to figure out what it may be. This has been going on for a couple of months now. Any help in trying to figure this out would be appreciated.
