Hello, Welcome to Health Care Magic. Thanks for writing. I am Dr.Saddiq-ul-Abidin. I have read your question completely, i understand your concern and will try to help you in best way possible. I am sorry to know about what has been happening with you lately. According to the history you have given me and description of symptoms how they start , how they continue and how they cured i am of the opinion that you indeed seem to be having and allergic or inflammatory reaction to certain foods. Like other parts of the body tongue too can be irritated by certain chemicals contacting it which in case of tongue are foods. There are certain irritants in foods which can cause inflammation on tongue. The foods which you have mentioned in your list are foods which mostly have a preservative and have some ingredient among them which is canned. Canned foods can have certain irritants and preservatives which can cause such symptoms , you can avoid this problem by simple changes and care. Here I would suggest you certain measures which you can take to avoid this problem in future. 1) Avoid preserved and canned foods. 2) Make a list of foods which irritate your tongue and avoid using them. 3) take an anti histamine like Citrizine 10mg at night daily when you are having inflammation. 4)Brufen or tylenol can also help in relieving pain and inflammation. 5) Nsaid gargle solutions and Somogel can help too in relieving pain and inflammation. This problem can be easily controlled and cured but will need active care and attention. I hope this answered your question.If you have more queries I am happy to answer.Otherwise rate and close the discussion Regrads.
