I have been having these sharp, breath taking pains in pit of my arm followed by my skin hurting to the touch from my left albow across to my right?

See your doctor: Problems like these can only be correctly handled by your doctor in person. He/she needs to listen to you, perform an examination and possibly run labs or other tests. That's the only way he/she can find out what's going on and what to do about it.

Hmmmmm : Sounds like you have breathing problems? If you think it is causing shortness of breath go to the emergency room pleuritic pain is non specific - look it up it is from the lining of your lungs i am not sure you are having pleuritic pains but usually they get worse as you take a deeper breath.
