I will be laying down and get up light headed. Although it's getting worse. yesterday I got up from my bed since I was just resting while listening to music and once I stood my I was extremely light headed and my eyesight grew blurry and I had to lean against the bed to keep myself balanced. I also have a vitamin deficiency, which I have to take these vitamin pills for, these other pills for my bones since I have bone cyst in my legs, along the fish oil pills, one each day since the doctor had given them to my mother for me. Now I've taken blood test before which found my vitamin deficiency, and X-Rays for my legs finding bone cyst... But what's the light headed thing from along with headaches?? I get them way to much... I want to know what's wrong. I'm getting a CAT scan soon but is anyone having this problem, is it the medicines? Or something that I'm doing that's causing this. To be honest I'm a bit scared about having these I'm the only one in my household and I keep asking why me, and I fear if it's going to be something really bad. I don't want to have these problems my whole life either.
