I have had a lot of symptoms to an illness that has not be diagnosed. I have rib pain on my left when I breathe, a headache, nausea, had a stiff neck, had black in my mucus (not a smoker), and i've been dizzy. I went to the hospital twice...all blood work and chest xrays came back perfect. i've heard the flu...but im not sniffling or coughing rite now. then sum1 suggested an inner ear virus. any ideas? thanks
