I've been sick for 3 days now and I though it was the flu, but now Im not so sure.
My symptoms are: sharp pains near left lung, heavy breathing, it's painful and very hard for me to swallow, my mouth is very dry, Im fatigued/tired all the time and my headache is almost unbearable. And I had a fever of 102.8 farenheight(pardon my spelling) the first day I felt ill but it hasnt come back.

I took an advil but it didnt help, should I go to the doctor/hospital or just suck it up?

I feel I should mention my sister(whom I live with) is in the hospital with pneumonia. I am a female minor(if that means anything).
