I was rear ended 10 years ago. During my ER visit, they found congenital birth defects in my C1 and C2 vertebrae. The radiologist's report states that my C1 is partially fused to the base of my skull. There is a deformation in the arch of my C1 and a deformation on the left side body of the C2. I remember the neurosurgeon saying one of those issues is rare in that part of the spine and that he had not seen it except for in the lumbar spine. It wasn't surgical at the time because I was a symptomatic. Now, I have been getting pain and tingling from the right side of my neck all the way down to my fingers. When I cough, I get twinges down my thighs to the knees. When I cough, I get extreme pain from my neck to my hands, and my arms go numb. I have been having migraines daily as well, and this was not typical before. The migraines are always behind my eye. Is this connected to my birth defect?
