Congratulations, Keith! Let the countdown to BAHA gotcha day begin!!!
Sorry none of us remembered to tell you about the huge "head dress" post op. I actually had a BAHA "hat" myself - pictures are posted on this Forum somewhere
My hat didn't bother me at all, but I only wore it for 24 hours post op. What you had sounds like the mastoid bandage I had wrapped around my head after my AN surgery - and I still remember how tight that was, so I feel for you.
The dried blood on the bandage is perfectly normal - most experience that. Typically this bandage is held in place by a round, white plastic "cap". Do you know how long it will be before your doc removes it? or lets you remove it? My doc removed mine 1 week post op - and once it was removed, I didn't have to wear it or the bandage anymore.
If your cap and bandage won't be removed in time for you to return to work, you might want to call the doctor's office and ask if you can replace the bandage with a piece of gauze (like Lori suggested) and then just put the cap back on. The main function of the bandage/cap at this point is to protect the still healing BAHA site. As long as you protect it, I don't think the doc will mind if you replace the bandage. But, obviously, don't just take my advice - I have no medical degree - please check with your doctor.
