What Causes Night Sweats And Sharp Pain In The Hip Area?

hi, i am a 31 year old female for 4 years i have had on off night sweats. I wake up saturated andn then need to pee. then I go cold and have to get back into bed. Since begining of may this year, I have had bad sharp pain in left hip area when walking. First doc thought it was endometriosis, I had bloods done they where normal, I had a internal pelvic scan, that was normal, I have seen a gyno and now on my mercillon pill back to back, still no improvement. Seen another doc, who sent me for xray on hips, turns out i have deterioration of the hips! But now on diclofenics and solpadeine for pain. they are not working great. Still in pain. still have night sweats. what could be wrong?
