I have recently had numerous ongoing symptoms, starting with serious vertigo and was put on a medication which helps occasionally. I do not get vertigo often, but when I do, it's bad enough to keep me from driving. I have since developed soreness like whiplash in the back of my neck and headaches. Not to mention trouble falling asleep and staying asleep because of horrible snoring. I am having some blurred vision as well. I am a breast cancer survivor of seven years and have had chemotherapy. Can chemotherapy cause Parkinson's? email is YYYY@YYYY
