Does generic morphine cause a rash that itches?

YES! It does! and it's driving me crazy!

I had surgery yesterday (Tubal Ligation) and they gave me some as pain relief when I came to and have been itching eversince!

Operation was at about 3:45pm yesterday and it's now a day later and it's still affecting me! Right down the itchy nose!

I might actually be allergic to it (??) because this has happended each time I've had it, or Pethidine (during Labour). Each time I've also vomited afterwards.

EDIT: No, you're not allergic, i was in hospital for 6 months, i used ALOT of morphine, and i was VERY itchy! Yeah, the nost, the arms, the torso, thighs, and my whole face, they were the most intense places!
