Pain
"I received Dilaudid through IV while in ER for kidney pain. The pain relief was very fast and effective. However, I had noticeable side effects - that disorienting whoosh effect mentioned by another commenter, severe dizziness, nausea and blurred vision. When admissions asked me to sign paperwork I had significant trouble raising my arms and holding the pen, but I was able to sign my name with a great deal of concentration. Getting out of bed was very difficult when they asked for a urine sample. I needed quite a bit of assistance from the nurse to walk across the hall. All I wanted to do was lie very still and minimize the dizziness. It took about 8 hours for this effect to go away."
