I definitely would follow through with your doctors and push for more testing! My best friend had that same thing happen to her abdomen about 18 years ago. She had to go through so many doctors to find out what was causing it. She was finally diagnosed with non-Hodgkins disease. I want to give you hope and tell you that she is still alive and living a full life since that diagnosis. She has had chemo a few times but always came back from it, as hard as it was. She exercises and always eats very healthy. She knows that she will always have it but she does everything to fight that disease!!! She has succeeded! All of my best wishes for you, and please be encouraged by my friend’s story. However, definitely investigate further! MaryAnn from Boston
