Any one here ever have a trapped nerve that causes excruciating pain in the shoulder blade/shoulder region that radiates down the arm? If so any advice on how the hell I can make it stop? Codeine is barely doing a thing and if I take any more I'm going to overdose, can't even sleep for more than an hour at time as get woken up by the pain. Heat applied to area helps only a little and ice makes me howl in agony. Don't know whether to make an emergency appointment at Dr's on Monday, if so should I ask for medication specific to nerve pain like Gabapentin or Pregabalin? Reading up it seems Opioid pain killers are fairly useless which does seem to be the case. Honestly at the end of my tether, any advice would be much appreciated!
