I have had a neck injury for number of years. Bulging discs and loss of the normal curve. I am afraid I may have developed a hernia causing the acid but I wanted to let you know I have had many of your symptoms since this injury. Blurred vision which has gotten much worse lately, dizziness and vertigo episodes. Back when I was trying to get treatment done, the pt's and Dr.s treated me very poorly because they didn't believe the dizziness and blurry vision contributed.
