Hello and welcome to Healthcare magic, In your query you have not mentioned whether you are still continuing medication or not. I hope you ae on medications which can be tapered slowly before stopping with regular follow up from a qualified psychiatrist. Experiencing mild difficulty in swallowing once in a while do not appear to be a part of panic attack. Maintain good food, adequate hydration, ensure sleep hygiene, and do some relaxation techniques to maintain improvement. So as far as I can see, there is nothing in you that you should be worried of. Hope I have answered your queries. Feel free to write if you need further clarifications. Get well soon.
