I'm a 21 year old male, and so I have sickle cell anemia, and I've been in the hospital over 100 times. Now, I went to the hospital this one time, and they gave me something I never had before which is dilaudid. I weigh no more than 160lbs, and it clogged me up to the point where I couldn't go to the bathroom, nor get an erection. So, I got over the addiction that time, and I noticed that I could get erections again. Now, I went into the hospital again a couple of months ago, and I told them that I was allergic to dilaudid, and they still managed to give some to me while I was half sleep, but I stopped them from giving me the whole injection. So, I have an injection to morphine in which I'm working to get off of, and wondering why is it that I can't get an erection?
