I finally heard from my boyfriend. He head is fine! He has an ear infection and a sinus infection and they said that was why he felt the popping in his head. I am so, so relieved. I was freaking out. I tried calling him at 9 and 10 and he didn’t answer. I didn’t know cell phones still interfere with medical equipment. I thought they would have figured out some way to fix that by now. Anyway, he will be home session as he gets discharged, which I hope doesn’t take too long.
