I was reaching on the kitchen top cabinet for a dish, really reaching, and a snap popping motion happen on the mid lower left back side of my neck. Afterwards, on that side of my neck felt really loose and my right side felt more tense. Well, the next day I woke up and felt the same; but, further in the day the same spot felt sore. I believe it got adjective from turning my head throughout the day. But, is it something I should worry about right away? Will something like this heal itself if I keep the head motion limited and such?
