<s>[INST] I have been suffering from chronic sever lower back and hip pain for about 4 1/2 years now, but all the physicians I have seen seem unable to find the cause, or literally tell me its all in my head. I have seen at least 7 doctors and had every test you can think of aside from an MRI and no one seems to find anything thing wrong. This year I was diagnosed with stage 3 endometriosis, and my OB has chalked most of the hip pain up to the imflamation involved with my disease, but I dont think he right. I hurt constantly and have numbness in my legs feet and lower back followed by a burning sensation regularly. I have 3 kids at home that I dont get to play with without having to stop regularly to rest and now I having to take depression meds because I feel like Im crazy. Please help!
