Hi everyone! I havent posted here in a little while because I have been trying to work through this kind of on my own. For about two weeks now I have noticed my upper back crampingon and off and what I think is my diaphragm feels really tight and it seems to affect my breathing. I cant seem to get a good deep breath. I also get winded more easily. It almost feels like I am tight from left side of throat all the way to my diaphragm. I probobly dont have to say this has got me more than a little worried. Has anyone on here experienced this? Oh also it feels like my heart speeds up a little too. I would really like to hear from someone this has or does happen to as it worries me alot considering what it could be. I have been going at this BFS? hopefully for 13 months now and if you have seen previous posts I have and do have alot of wierd symptoms like most people here. I am on edge again and need advice and reasurance hopefully. Thanks for any replys! Barb
