I agree with all the above,and would see your Dr or ER immediatly,,Some heart attack symptoms carry the same signature or The culprit may well be the meds,,opiods are well known to cause shallow breathing,,I use percocet at times as well,and 50% of the time, I have the same reaction,,if you want to know[field test] for sure,,,,ask yourself this question, " Does the shallow breathing happen soon after taking the percocet{within 15-40 minutes??? thats when it hits me,,} please be carefull,and get checked out and let us know what the Dr says,,,,,,bobber ,,I dont think its wise to wait 3 weeks to see your Dr and Dont worry about what your familiy thinks,,please go to the E.R
