Dear Dr. Nagler, Thanks in advance for your help. I went to get custom ear plugs fitted today and I fainted when the putty was put in both my ears. Googling my symptoms (sudden extreme tiredness, nausea, feeling of 'hotness' in the head) I read that fainting comes from loss of oxygen supply to the brain. The audiologist suggested I see a doctor as no-one had ever fainted during the putty procedure before. I'm a bit concerned about it because I don't normally faint. I was definitely scared about the procedure, but I did actually feel like for some reason, when the putty was in my ears, it was almost impossible for me to stay awake. After the audiologist woke me from the initial fainting, I had to push my nails hard into my leg to cause me pain so I wouldn't fall 'asleep' again. After putty was taken out I had to lie on the floor for a minute to recover, then after that I felt okay. Do you know why this might have happened? The audiologist peeked inside my ears afterwards and said everything is okay. He thought it was stress/anxiety, and sure I was scared, but it did feel like it was something about the putty in my ears that made it impossible for me to stay awake. I've got relatively recently (3 months) diagnosed tinnitus from too-loud music. I've also got TMJ - but that's been chronic and longstanding. Thanks so much.
