I have had left side pain and tender ribs and back left shoulder blade when touched, it also sometimes is in the chest area.I have gerd and don t believe this is the problem.I experience burning on the left side with a light headed feeling and have been to er multiple times and was told plurisy or acid reflux.I also have had some what is believed to be hemroids bleeding during bowel movements that is getting better. The main issue is the side and back thing and I have lost about 55 pounds in three months changing the way I eat and don t drink anything but water ...
