hi, i'm under alot of emotional stress, and woke a couple of days ago with pain in the right side of my chest felt like it went though my shoulder blade, and my right arm was painful and difficult to move, just thought i had slept funny, this lasted all of the day, the morning after i had the same no better, i walked to shop a 5 minute walk, and struggled breath felt like i was going to collapse, that was couple of days ago, i have rested since, but still have dull pain in my chest but my arm is now ok, and i get out of breath very easy just going up and down the stairs, when i rest i can take a deep breath with just a mild pain in the right of my cheat, but if i have been up the stairs, and find it difficult to breath, taking a deep breath then is pain full, i am 31 years and near ideal weight, i do smoke, but don't really drink often, i haven't seen a doctor about this is i don't want to waste any body's time with what could be nothing, an idea of what it could be and what i should would really put my mind at ease,
