Help with burm

[confucius]

I recently bought a female burm. She's between 8 and 9 feet. Very skinny, has basically nothing on her. Like retic skinny. Almost colubrid like. Her underside caves in and her skin is very baggy. The guy I bought her from said she recently laid eggs. Is this what they're supposed to be like after laying eggs? She has a big scar on her face, I have no idea what it's from because he said he didn't feed her live. When I brought her home I put her in quarantine. Today I noticed she has a scab on her gums. All the substrate was also sticking on around the front of her mouth. She's extremely restless. I thought I noticed mites today so I soaked her, cleaned her enclosure, washed it with mite spray, and wiped her off with a towel with mite spray on it. I don't see any more, but I really don't know what to think of her anymore. She doesn't stay still. She continually pushes up on the enclosure top. I notice sometimes she drools a little bit. I don't see any other signs of RI. Her temps are fine. It's getting really stressful because I don't know what's wrong. She doesn't do anything odd besides act very restless. Does anyone know what's up?
