Welcome to mamapedia!
If the hospital has done blood tests - yes, they are 100% accurate. You either have the HgH there or you don't.
Back pain? Kidneys. Especially lower back pain.
Do you drink a lot of soda?
Your stomach moving? Could actually be the food digesting in your stomach and passing through your digestive track to the intestines.
A fatty mass on a hernia? It's a fat build up on the muscle or organ (intestine) that is protruding in abnormal place...
Heart racing is anxiety.
Get to your Primary Care Physician (PCP) and get a full check up done - hormones, etc. If you are trying to get pregnant you could be convincing yourself you are pregnant and having psychosomatic symptoms.
I don't know how old you are, if you are married, how many kids you have or don't have...so that's all I can give you...
