I have gone into shock with Percocet,Demerol,morphine, codeine When given for pain to the point I was unconscious. What can I tell Dr's/ER I can use for severe pain. I am getting a medical ID Incase I can' t speak in case of an emergency. My B/P drops drastically, I sweat and go unconscious. This also happens when coming out of anesthesia. I just spent 2 days in hospital because this happened and I had a bad EKG and have 3 stents in. Went in with a twisted ankle ans severe sciatic pain in foot and leg after a bad fall into my back. I also have a milder reaction to alcohol.View Thread
