@turkay1-- I'm not sure. Are you the one with these symptoms? Did you see a doctor?
I know that some viral infections like meningitis can cause throat pain, head pain and overall fatigue. But viral infections also cause fever. Do you have fever?
I suppose it could also be an upper respiratory infection. When I was young, I would get upper respiratory infections in winter. The infection would always move into my throat and ear and cause throat and ear infections soon after.
The throat, ears and nose are all connected, so an infection in one can move into the others easily. As for head pain and headaches, those are common with many illnesses.
I don't want to scare you but at the more dangerous side of the spectrum are diseases like cancer, such as cancer of the mouth, thyroid or lymph nodes. So you better get checked out.
