All last week I had horrible upper back pain between my right shoulder blade and spine, which progressed this weekend to the point of shooting pains up my neck and down my right arm sporadically. It started out minor and got worse. It even got worse this weekend despite not being physically active at all.The pain is there no matter my posture, and gets worse with movement. Tonight is going to be a show because of the 3 day weekend and Labor Day sales. I know if I go to work I'm going to it up even further. I'm out of vacation time and sick days and my supervisors are the most unaccommodating people I've ever met. I told them last week that my back was in pain and I needed help loading but they insisted I suck it up and power through and not be a pusillanimous. What should I do? I can't make it to a doctor until Thursday.
