Hi Rex, I can understand your concern. It happens many times that a single person is allergic to more than one substance or one substance but that substance is used in many things, so it makes a person allergic to many things. As you now know that you are allergic to prawn, do not keep trying it as every time it will cause an allergic reaction and there are chances that it will increase in severity causing complications. As you do not know other substances that may be acting as allergen to you, I would recommend you to go for a blood test for allergy. It will detect all the substances that you are allergic to, so you can take care to avoid them. In addition, for the burned area inside the mouth, you can apply Endocrine Gel (McCoppin) 3-4 times a day. Applying it before meals will make consumption of food easier. Also, you should keep antihistamines such as Levocetrizine 5 mg (Exocet) or Loratadine 10 mg (Forfeits) always at hand, so you can start it as soon as reaction starts to develop. I hope this information helps you. Thank you for choosing Chat Doctor. I hope you feel better soon. Best,
