When I was a baby, probably about a year old, I had a CT scan, or an x-ray (can't remember which one) of my head. Then, last year, I had a CT scan done of my head again on 5/31/07. They found a 2 ml lipoma (fatty tissue). They didn't think much of it, so on 6/18/07, I had an MRI done on my head. I know MRI's don't use radiation or anything, but still. Anyway, if you read some of my other questions, you'll see my list of symptoms I've been having. I started getting heartburn, headaches, and tingling sensations before the CT scan, But all the other symptoms came after the MRI's and CT scans. Anyway, I got diagnosed with ehlers danlos syndrome, but I've been having some other issues, so my doctor wants me to have another MRI of my brain and spine. She also wants me to have an x-ray of my cervical, thoracic, and lumbar spine. I told her I already had a CT scan and an MRI done, but she didn't seem worried about me having more x-rays done. She also thinks I should have a gastric emptying scan done (since I've gotten eggy burps, vomiting episodes, and dizzy spells since I was little). My GI doctor thinks I should also have an endoscopy and a colonoscopy done. Please tell me, do you think having all those x-rays and stuff (minus the endo and the colon and the MRI) could put me in any danger of developing cancer? Has there ever been a documented case of anyone catching diseases like HIV or hepatitis from unsterilized tools used for an endoscopy and a colonoscopy? I remember after I had the CT done, for about a week, one part of my scalp burned/hurt whenever I touched it. Please tell me what you think the risks are for having 2 head tests last year, and now having 2 more head tests plus an x-ray of my spine. Thank you!
