A month ago, i've intense pain on my throat, every breath feels like someone used a knife to carve his way through it, I was told by doctor to let it sit out for a week and see how it goes. About two weeks later the pain went away but since then i started to feel the pain here and there, especially after i have intense exercise, my nose will often have mucus build up and i'm constantly feeling weary and dizzy, any idea what kind of doctor should i visit or any advice for my symptoms? My GP always told me its normal so i pretty much give up on visiting them and repeating my problem.
