I Have A Sicky Feeling In My Chest, Please Suggest Me

Hello There, for some reason i keep getting headaches all around my head. Theres a bump on top of my head it doesnt hurt to touch it but that's where sometimes the headache is. It is other places like the back of my head or near my neck or at the left or right of my head and other places. I also have nasuea, i have a sicky feeling in my chest and sometimes w here my ribs are. Sometimes the headache is worse then other times, i went to see a doctor checked my eyes and ears. Said it was fine. When she got my to read letters from far away i covered my left eye, right eye was fine. Covered right eye, the left was a little bit more blurier. I also sometimes have been shakey aswell and shivering. I really need to know what this is. Its beeen going on for about 4,5, 6 weeks or so. What could this be?
