i went to my pc dr last Friday as I noticed a lump on my clavicle...left side. She ordered lab work and an ultrasound. Lab work is fine and the US shows possible arthritis. She also told me at my appt that my left ear is bulging and i had some post nasal drip. I was tested in August for allergies and was found to have an allergy to mold. I started taking OTC Claritin 24 hr and Aleve for the "arthritis" I am wondering if my ear and lump are connected? I also have a feeling of fullness in the center of throat. I do not have a thyroid disorder as my lab work has been normal for that as well. The lump is not painful but my ear and the side of my neck give me some discomfort....as does the fullness I feel in my throat. I have always been a non smoker, drink 2-4 drinks per week, take no meds and have no medical disorders.
