T.F.
I did not experience what you are talking about.
My last mammo was the one from hell. I thought my ribs were cracked, I could not move. I complained and they acted like it was nothing then charged $500 to do a scan and it was not cracked but there was heavy bruising inside. It took about 6 weeks before I felt normal again.
Oh and I bitched about them charging me when I wouldn't have been there if it weren't for their error. They relented.
Sounds like you may have an allergy to sonething they cleaned the machine with. Don't back down and don't let them charge you.
