MORPHINE vs HEROIN

[msdope]

Years ago I had several operations. They gave me morphine. I recall screaming my head off. They looked at me in recovery, and said I had a rash and I was allergic, and gave me Dilaudid, and I was just fine. Much later after I had been doing heroin I had an accident, and they gave me morphine. No good. It didn't help the pain a bit.

Now I put on medical records I am allergic to morphine. That's what the Doctor told me so I put it down. I am now told I can't be allergic to morphine if I used heroin for so long. I'd have broken out in a rash, and stopped breathing. Blah, blah, blah.

I've been clean now for a long time, but if I am in serious pain in a hospital the hell with clean, and sober. Is it possible to be allergic to the morphine and not to the dope? Just wondering. Thanks.
