I hear bones grinding in my back

I am a 50 year old female that smokes about 30 cig, had hysterectomy at 29, do not take hormones, and bone density scan in 01/2011 did not show any osteo. When I twist my body, I here what sounds like bones grinding together in my back. I can't say that it hurts but the sounds are enough to alarm you. My question is: should I be alarmed?

Hi there!

Well, without a detailed clinical evaluation it would be difficult to comment specifically on the situation. Possible causes that may need to be considered include degenerative changes associated with the spine, muscular causes etc. It may not be something to get alarmed, though I would suggest an evaluation by a primary care physician initially and depending on the cause required, it can be managed accordingly or specialist care may be sought.
Hope this is helpful.

Take care!
