Interred.
I had a similar situation with my neck. I was laying in bed and suddenly got a severe pain in my neck and shoulders after turning onto my side... your description of a "tight" feeling is pretty accurate to my symptoms. It progressed fairly quickly and traveled down my right arm causing pain and tingling in my hand, down into the thumb, ring finger and little finger. My arm hurt intensely as long as it was out straight. I found that curling my arm up to my chest help to relieve the pain. After about 12 hours of hoping it would subside I finally went to emergency room and was admitted. During the stay I was put in traction and given moist heat packs and massage, and had a CT scan of my cervical spine. A neurosurgeon appeared in my room on the third day and showed me a set of slides from the CT scan. The disc at L5-L6 had a chunk broken off which was floating at the nerve root and was pinching the nerve. He asked if he could operate... I replied "YES" without even asking what would be done. I just wanted the pain to stop at any cost. The neurosurgeon performed a laminectomy and foraminotomy, removed the broken piece of disc, then took a plug of bone from my hip which was placed in the disc space. The surgery was successful, but I do have nerve damage from having the root pinched at that level. The remaining residual pain and numbness is much easier to live with than the way it was. Definitely minor in comparison. I hope your issue is not as severe. Good luck to you!
