I have been experiencing upper left abdominal pain that radiates to my back for almost 3 weeks now. I sometimes feel as if I cannot take a deep breath, kind of feel like the air is not going all the way into my lungs (almost like after having an asthma attack) Also sometimes I will almost feel like I am starving but once I take 2 or 3 bites I am immediately full and I feel a lot of pressure. It is not related to certain foods or acid reflux. The pain does occasionally wake me up at night and will almost be unbearable for me to lay down. I had a CT scan done a few months ago to check my kidneys because I do get kidney stones but my kidneys were fine, gallbladder was removed in 2003 but it almost feels like the same type of pain I got from both of those. I have been to the doctor and they are suggesting me have an endoscopy, anyone have anything similar to this?
