I have been suffering for about 8 months with my mouth going through a series of outbreaks. I get a burnt feeling inside my mouth as if I had drank very hot liquid, mostly under my tongue. My lips swell like I had them injected. I also get sores that appear in the corners of my mouth. Sometimes patches below my lips that itch and are slightly rough. The inside mouth area feels burned for about a week. The swelling goes down after about a day. Then my lips peel for about a month. This is very painful.
I am keeping a diary of what I eat and when it happens. I have many allergies and asthma. One thing that this reacts like is a shellfish allergy which I have. I also have an allergy to Triclosan which is in antibacterial soap. If I get it on my hands they react like I have poison ivy or oak. red raised bumps, filled with fluid. It feels better if I scratch and make it bleed. The fluid oozes and then I break out in other areas that it touches. Running the area under hot water feels good. Putting calamine lotion helps the itch but it takes a month or so for it to go away. Chitosan contains triclosan. Chitosan is a Sugar that is obtained from the hard outer skeleton of shellfish, including crab, lobster, and shrimp. It is used for medicine.
I recently read this online:

[A case of anaphylaxis caused by the health food chitosan]

Chitosan is a linear polysaccharide with about 10(5)-10(6) molecular weight existing in cell walls of zygomycetes. Chitosan decreases serum neutral fat and cholesterol levels and has dietary fiber action, and many products have recently been sold as health foods. Here, we report a case of immediate-type allergy for chitosan-containing health food with a review of the literature. The patient was a 47-year-old female person who developed systemic urticaria and difficulty in breathing after oral ingestion of chitosan. Since skin tests (prick test and scratch patch test) were positive, the test was done using another commercial chitosan, and was positive. The patient was diagnosed as having chitosan-induced immediately-type allergy, and was instructed to avoid ingestion of chitosan. The patient has developed no symptom thereafter. Regarding allergic reactions to chitin and chitosan, contact dermatitis induced by chitosan-containing cream has been reported from France and Portugal, but to our knowledge, there has been no report of immediate-type allergic reactions. Chitosan is a polysaccharide, not protein, but may have functioned as a food allergen because of its molecular weight and general properties.

On drugs.com It states "Side Effects
Those allergic to shellfish also may experience allergies to chitosan products"
