I ve been taking two Percocet every four hours for the past two days now after getting my tonsils and adenoids removed and I ve experienced mild to medium itching, at times to the point I couldn t sleep, and now it feels like my heart is racing and palpitating and I cannot breathe normally. I feel like I need to let my breath out and push for longer to get it all out before I can take another breath and my tongue has randomly been gliding against the roof of my mouth when I m half asleep then stops. Is it safe to continue taking this medication or should I call my doctor?
