Hi, I have been suffering with symptoms for 3 weeks now. Tend to feel off balance, dizzy all day My ears feel pressured, and all around behind my ears, into the top of my neck, base of head, and this area hurts slightly. I have pressure above my eyes and my nose, sometimes i feel movements in my nose. My nose is not blocked or runny. I get occasional headahces, round my temples and forehead. I sometimes feel weak or heavy. And some days i will be feverish. Yesterday i had a pain in my left side of my chest, its now a dull ache and slightly tight chested. I had blood tests all clear, and ECG all clear. Could this be a problem with my sinuses, even without blocked nose?? Or a virus that is now infecting my chest??
