Tongue pain since 2017
I have been facing lots of weird medical problems for years now. They come and go and I dont know what is wrong. From 2014 to 2017 I used to get fast heartbeats, in 2015-17 I started getting lots of hives, in 2017 onwards I have this tongue problem as attached. I was in school until 2016 and after coming out of school, I gained fat very fast that by 2017 I reached 64 kg from some 54 kg but my neck gained fat weirdly (see attached). I have tested my thyroid and it was normal. My blood pressure and sugar level comes normal as well. I also get facial bloating whenever I eat pizza so I thought maybe I am allergic to lactose but then I eat paneer and milk without any problems. I don't like the smell of curd and I get an instant urge to vomit just from smelling it but I can eat it without problem when the smell is not there. I don't like buttermilk at all. What exactly is wrong with me?
