What causes pain and cracking in knees?

[surf22]

I have been experiencing cracking in my knees and back for some months now. Can there a disalignment in my spine that can cause knee pain?

[achyone]

Oh yes, and vise versa too.

Depending on your age, you could have arthritis - remember that as you age you will get some cracking noise in the knee as the joint ages. First see the ortho so an xray can be done to see how much junk is in your knee(s)

Margaret,
the popping from your knee could be due to cartlidge break down in the knee it self. You need to have it Xray'd ASAP. The pain could be coming from the constant  rubbing of the bones. Have you try'ed Flexa-min with MSM and Chondroitin ( Over the counter).

The muscle pain could be due to many things ranging from poor circulation, cramping, burning thigh and possibly lactic acid build up in the muscle.
