My boyfriend has had back pain for the last 4 months. We have gone to the e.r. here numerous times and each time they give him a b.s. diagnosis and give him muscle relaxers which don"t work. I truly feel like these doctors and nurses genuinely do not care about their patients at all. Not once have they actually tried to figure out why for the last 4 months that his back has been hurting so bad he can barely move.
