My BIL had to go to the hospital last night, and he's still there. He has been puking and has had diarrhea since Super Bowl. He went to an urgent care two days ago, but they didn't know what was wrong. Everyone (including his parents who drove down from Charlotte yesterday afternoon) finally convinced him to go to the hospital last night, and it was discovered that his intestines are twisted. The doc is going to see if they untwist in the next day or two, and if not he will have surgery. He is on morphine, and they are trying to control his potassium level.
Best wishes. I came down with a case of cellulitis recently, which is part of the reason why I left the board for a bit. I relate the story because I hope the hospital helps, and if morphine doesn't help with pain, tell him to request dilaudid, which is what I wound up on in the end. It's hydromorphone, and I actually can't believe morphine is going to help him, but I am NO doctor.
Best of luck. Make sure to advocate for him. They're sending PA's instead of doctors around on rounds these days. It's silly, and wrong. Advocate.
