Hi Seven: I am going through the same symptoms. I am actually going to a endoscopy tomorrow to see if they can find out whats it all about. I was diagnosed years ago (I'm 52) we are are talking in my early 30's of IBS and after having a colonoscopy done in December 2010 found i have Diverticular. And from there is just gets worse. I have discomfort in my ribcage area to the middle of my breast area(bone) with it being tender to touch and the wire bra doesnt help but gives a tiny bit of relief to remove it. I expand to where i feel like I am 4 months pregnant and some shortness of breath, especially after i eat. Theres that word eat!!! Not sure what to eat anymore. I'm not bad in the morning but as i approach the noon hour and on its like i start to balloon out, also chest discomfort and a gagy feeling. If i do anything physical like vacuuming or racking the lawn that requires that type of movement it becomes painfull, yet cutting the grass doesnt.
Its a darn mystery that i hope i get a answer for. I also seem to have a buring sensation on my left shoulder blade dont know if thats related or not. Although there have been times when its kept me up at night but they are far and few between thank god!!! I am presently on Nexium one a day and apo-domperidone 3 times a day. Although it seems to keep it a minimum its still there. Some days extreme discomfort but I have a high tolerence of pain but enough is a enough. Hopefully tomorrow i will have some sort of a answer, but by reading alot of threads lately it seems that even the doctors dont know what to do and give.
