Hi. I am a 31 y.o. female, 50 lbs overweight. I have hypothyroidism and high cholesterol. I have been havign mild chest pain on and off for a month or so, but didn t think anything of it until a week ago (on a Monday). It was severe enough that I couldn t concentrate and accompanied by nausea. It starts at my breast bone and curves upward towards my right shoulder. It feels like a tube of pain and also radiates into my back between my spine and rt shoulder blade. It also feels as if something is pushing on my windpipe at the bottom of my neck. I went to the Dr. same day and he was sure it was a gallstone attack. I went in on friday for an Upper GI and Ultrasound. The Upper GI was normal and the ultrasound showed no gallstones, though they did see a few benign spots on my liver that they are recommending that I have looked at via MRI. I am assuming this means that it is not my gallbladder causing the problem then. However from Thursday through Saturday I had yellow diarrhea (it s now Monday again) and thought the chest pain has lessened it is still there. It doesn t get worse or better with position, exercise or eating, though it is a little more uncomfortable with deep breaths. I am feeling increasingly tired. My Dr s appt is tomorrow for follow-up, but the fatigue has me a little worried. I also belch excessively but have read that this may be a side-effect of the Lovaza I am on for my cholesterol. What do you think could be causing the chest pain?
