I Have Lived In A Basement Apartment For 5 Years.

I have lived in a basement apartment for 5 years. Several months ago I had very swollen painful glands in my neck for a week. I was also lightheaded borderline dizzy occasionally and I was somewhat hyper lots of energy at times. When I went to the doctor I was diagnosed with chronic sinusitis which I have never had. I was also advised my blood pressure was up the top number was 120 and another time closer to 150. I had given platelets at the Red Cross for over ten my top number was almost always barely over 100. I still occasionally have tenderness in my neck(swollen glands) and occasional hyper feelings. I have not had my blood pressure checked since January. I am considering another doctor since not comfortable with the diagnosis of sinusitis. Could this be radon poisoning?
