question: Hi I have slight pain and discomfort in my upper back bewteen my shoulder blades.  Also sometimes I having trouble taking a real deep breath?  Are the two things related?  I am 37, 5ft 3", 8.2 stone, and last year I had seven epileptic siezures (this has now been related to mercury poisoning as the very first ever siezure occured a week after I had dental treamtent that turned out to have been done badly). Thanks.
