Cracking of the left knee

Hi

I have recently started doing more exercise and was on a cross trainer, after I had finished there has been cracking in my knee. It isn't painful but i can hear and feel it crack.

The reason I have not been to the GP is that i am joining the army and if it shows up with joint problems on my medical history they might cancel my application.

I have heard of runners knee, is this a possible diagnosis

Thanks for your time

Sounds like you were just running with a bit to much quads domination on the cross trainer. This is probably a simple alignment issue and a goos lower limb stretch should ease things back to normal. I shouldn't think that this would be an issue for the army unless it is accompanied by a former injury.

Is there any stretches or exercises that could help?

Thanks
Ste
