Just yesterday, i noticed a sharp pain and pressure in the back of my throat and right under my jaw bone every time I breathe deeply. Recently, I've noticed the pain every time I get out of bed or sit up too quickly. Sometimes, it even will randomly throb right under my jaw or when I hold my breath for anything, like to cry or to yawn. My throat isn't scratchy and I haven't been coughing but it feels like my throat shrank to half of it's size. About a week ago, everyday for three days, I had a very painful headache, always in the same spot on the top right side of my head. Then, yesterday, I felt sick to my stomach and my ears were going in and out and I began to feel dizzy. Please help me, I'm really worried.
