The other day my legs became like jello and I was very dizzy. I went to the hospital because I was very scared. I never had anything like that to happen. It took a little while before I could walk again. After the hospital did an EKG, chest x-ray, ct scan, and bloodwork, they came up with the diagnosis of a sinus infection. I am having a hard time believing that's all that it was. I have had a cold, but have only been producing clear nasal drainage.
