External Beam Radiation anyone??

Just curious as to whether anyone here has received External Beam Radiation to the neck/throat area and if so if they could recount their experience with it....

I've heard from my doctors it's going to get pretty painful after the first two weeks...constant pain meds....feeling like I'm swallowing fire and glass :(

The week after next I start taking treatments 5 days a week for 6.5 weeks, so I'm trying to gather as much info as I can so I can get my game face on so to speak.

Hop you all are well!!
