I have been experiencing slight pain in my upper right chest (around the pec)since Monday after dinner. Actually I did the Stairmaster Monday pm about 30 minutes after dinner with my food not digested totally and completed 2 miles in 22 minutes. Right after I stepped off my right chest began to hurt slightly and increased with deep breathes. No real shortness of breathe of any other symtoms. Current temp is 98.5 and bp is high for me this am 120/71 and resting pulse seems high as well 84. I awoke yesterday morning and it had subsided and did not return until last night (again after dinner 8 pm) but I did not do any excercise at all this time. I slept uncomfortably and it still is sensitive this AM as I write you this email.
