BP Litterally rubbing her self raw?

My BP after a battle with mites has been rubbing get neck against anything in her tank and he has a sore on her neck. Has anybody ever had this? I'll try to upload pictures later she seems stressed out right now

She is probably itchy as she's healing from the bites. Also, are the mites completely eradicated or are you still treating? I treat for two months after I last see a mite since eggs can take 30 days to hatch.

I'm still treating. I sprayed PAM and spray her with reptile spray every 4-5 days but she's darting around the enclosure which is unusal for her. So I'm a little worried

That same area is swollen like a mosquito bite

Reptile Spray is a solution of salts that kills mites by quickly dehydrating them. It also stings like hell if you get it into an open wound. I don't spray it directly on my snakes, I spray a white paper towel and wipe them with it, let them crawl over it, etc. as it's less stressful for them than getting sprayed. Plus you can check the paper towel for mites when you are done.

Do you have her on PAM-treated paper for substrate or is she on aspen, cypress, etc.?

PAM treated cypress. As from what we could gather she was relatively mite free. But we ate still treating just in case
