I would think about what you want the dr's to do. Do you want them to prescribe some stronger painkillers? I think they probably aren't doing this because it is a bit of a slippery slope of escalating doses and before you know it you are dependant on some very addictive drugs.
If it is muscular, it's not likely that any sort of surgery would help (correct me if I'm wrong here), but maybe physiotherapy would help.
I think they probably aren't helping you as there isn't a lot they can do to "cure" your pain, they can treat the symptoms with pain killers, but there are other consequences of going down that route.
Hugs though, I'm sure I couldn't live with that sort of pain day to day, and I'm sorry that you haven't found a dr that you feel is listening to you.
