I have had a burning tongue since last Sunday evening. This makes it a week now. It started when I had a sexual encounter with a woman. We did not engage in high-risk behavior - no oral sex, but I did suck on her breasts. After that my tongue tasted something bitter and felt like it coated with something. She left the next morning to another state to stay with her family. I called her and asked her if there was something on her skin - body lotion, soap, etc. - she said maybe soap but she wasn't sure.

The tongue didn't really feel bad at first, just has a pasty texture. However, by Tuesday it burned like crazy. The sensation is exactly like drinking boiling water and scalding your tongue. Except I didn't drink any hot liquid and my tongue felt scalded for at least an entire day. I finally resorted to putting a little on my tongue to soothe the pain, sucking on ice cubes, and squeezing Vitamin E capsules on the tongue. All these helped greatly to lessen the scalding sensation. However, this is 7 days later and my tongue still feels scalded, although not to the point that I use sugar, ice cubes, or Vitamin E. Scraping my tongue against the roof of my mouth, it still hurts.

I'm thinking this feels like a chemical burn on the tongue. I have also developed chills in my body since last Sunday, as well as inflammation of blood vessels/tissue on the left side of my skull. I have taking Advil or Ibuprofen to ease the inflammation and it does work.

I am still worried about the chills and the tongue's sensation of being scalded still. What could have gotten on it? The woman I was with could have done something to spite me, by putting something caustic on her breasts knowing I would lick it (we had a tumultuous relationship). I pressed her but she would not admit to anything. I say this to say it couldn't be anything else because I haven't eaten anything or drank anything out of the ordinary.

Any ideas on what this substance could be? I called the national poison hotline and they didn't know. Could it be hand sanitizer (odorless)? Body lotion? Soap? Could it even be an infection of some kind - bacterial, viral, or fungal? My tongue looks normal enough, white coat, with red area where the burn is, but the red area doesn't look that bad. I did visit a primary care doctor last week and he said the tongue doesn't look unusual.

Another symptom I would like to mention is that since the tongue burning I feel a pain in the optic nerve of my left eye. Not too bad but enough to be noticeable.

This evening out of desperation, I just bought some Bentonite clay to see if I could absorb whatever it was that got on my tongue. I put some Bentonite clay powder on the tongue to soak up whatever residue is left, and drank a teaspoon mixed with water for internal cleansing. Do you this is effective?

Thank you.
