Ligamentous Creep Symptoms

Hello T-Nation,

I have been doing some bodyweight traction as done on the article here

I only did them in 10 second periods, however I have noticed that my lower back has been making increased clicking noises when I do this… When I first did this, there was no clicking. now whenever I do light traction, even when Im just pushing myself off the chair when I get up I notice loud clicking noises. There is no pain associated with it

I had a back injury a while ago if that makes any difference, any ideas?
Thank you,
Dan.
