In 1993 I broke my neck. My C4,5 & 6 were fused. Looks like screws, plates & chicken wire to me. I’ve had problems with left arm not working sometimes and neck pain. In 2007 doctors said the screw had backed out but was calcified so it didn’t need to be fixed. I have been having pain, not sleeping and headaches. Now they say it is loose. Current COVID-19 says no non essential medical procedures. I’m scared of becoming paralyzed or dying. How much time do I have to get screw replaced, caulked or other repair? Should I be concerned with time. Thank you.
