Whenever I lay on my back my left hip it frels like there is a lot of presseure then it pops 1-3 times it sometimes relieves the pain?

Xray. Need an x-ray for lower back and left hip; many disorder of the back and hip can present this way; mean time naproxin or Motrin can help the pain, and may be muscle relaxant like flexeril (cyclobenzaprine hcl).
