Actually i was doing pull ups about 1.5 years ago, i suddenly felt something streched & after that severe pain started in my neck... It was too difficult to move neck, it lasted for a week & after that i started feeling good although sitting or looking at one direction for long time gave me pain... But the pain has now increased, its even aches when i move my left hand... I tried sleeping without pillow but its not effective...sometimes i get relief for short period of time after moving my head left and right until cracking sound is heard.... I guess its some kind of pinched nerve, tough i don't know much about it... Please help me
