Hi, I am a 41 years old woman and am experiencing shortness of breath and pain in my left shoulder blade when I yawn or breath in deeply. I have a lot of problems with my nose (swelling, sinus infections) and have been told I may need an operation to reduce the swelling and correct a deviated septum. I m not sure if this is related but thought I should mention it. Also, this is a bit embarrassing, but I am burping a lot, which is not normal for me. Thanks in advance for any advice.... Laura
