The MRI needs to be evaluated by a radiologist or spine surgeon. It would be distinctly unusual for the only finding to be the “cervical spine was straight”. The MRI is not helpful for normal alignment as it is performed with you lying down in an unnatural position with the coil on your neck.
Pins and needles (paresthesias) in your arms and legs could be from the neck but also has other potential sources. If possible, could you send your MRI on a DVD/CD with a DICOM reading program to my office with a cover letter? I would be happy to comment on it.
