I have to be in work in under an hour. My back and neck hurt a lot. I cannot take the repetative nature of my job. I can hardly move by the end of the day because of it. I don't want to go to the company again over this- I am looking for a new job so I just need to hold out for a few more weeks until I get out. What are some quick and somewhat effective ways to mask the pain for a few hours? Why am I having such a hard time building muscle on my back?
