About two months ago I started having trouble with my vision. I cannot focus my eyes on anything, when I do, everything goes blurry. I have a constant headache and stiff neck. I am so lightheaded all of the time that it is hard to even stand up. I have tingling in my arms and legs. Anytime I do any type of physical activity, my heart beats so fast and I am so lightheaded that I need to sit down. I have also been short of breath for a few weeks. My ears hurt constantly and the ring all the time. I have been to 20 doctors. I had an MRI of my head, it showed a 1cm penial cyst but the doctors said it is nothing to worry about. I also found mold in my apartment, so I saw a specialist and he says that it is not the cause of my symptoms. Recently I have been so scared of what I have that anxiety and depression have set in. Doctors have talked about MS, heart problems, auto-immune problems, and increased intercranial pressure, but no one knows what is worng with me. A few doctors have said it is just depression but my body is telling me somethinf is wrong and no one will listen!!! I don't have any ear infections and my blood tests have come back normal.... PLEASE HELP I AM SO SCARED!!!!
