I broke my c-1 in two places after falling down a retaining wall in Aug. I have been in an Aspen collar for 8 weeks with MRI, CAT scan and X-Ray done during this period. I have tried to take the Aspen collar off for brief periods now that I am ending treatment but every time I do I get bad headaches, pain along the bottom of my skull and behind my ears. It even has affected my sinuses. Has any one else had this problem? The other strange thing is that the neurosurgeon is not suggesting any PT after the collar comes off. Isn't that strange?
