Hi sir I have a gone through an ACDF SURGERY or a neck spine fusion for c5 and C6 around four months back while sleeping my neck gives me a pain it's from day one but believe me doctors at fortis hospital who operated was a professional and have cured the main cause which was shoulder pain and arms disabled - was unable to lift my arm due to severe nerve pressure and pain. Please advice this small neck pain it normal and if so then how much time would it take to recover as sleeping is not easy for me.
