I'm a keyboard basher by trade and probably don't have the worlds best posture but I've never had neck / back trouble before that wasn't caused by violent martial arts techniques, until now..
Just over 2 weeks ago I woke up with a sore neck on the right hand side. I went to work and it wasn't too bad, though sudden movements were painful. Later that day I sneezed, instant agony. By mid afternoon my neck & shoulder area was in spasm, any movement caused excruciating pain and my shoulder was hunched up by my ear. I got a taxi home and the driver asked me if I wanted to go to A&E...
Painkillers and heat made it feel slightly better, the next day it still hurt to turn my head and riding was out. I had a massage session and asked him to concentrate on the neck back & shoulders. That left me all relaxed and sleepy with a lot of the tightness gone.
Since then I've been swimming a few times to try & loosen the area up but it's still not right. Sitting here now my neck still feels tense and I can hear/feel a crunching noise as I swivel it. Area between the shoulder blades feels tight as well.
Time for the Doctors and ask for a physio referral ?
