muscle spasm
"End up a A&E screaming in pain in neck & arm, any movement made it worse. Back there following night even worse, even though I was given 2mg diezapan & codeine. Zero effect. Emergency appointment with GP increased to 5mg. Lots of sleep but no pain relief at all, if anything got worse. 6 weeks off work. Seeing specialist for  CT scan and having something injected. This was caused by cheap nasty keyboards as speed more important than ergonomic keyboard or regular breaks to stretch or proper desks. Tired of being tired."
