I have had a clicking noise in both my ankles for the past 5 years. I'm currently 40 years old and it seems to be getting louder as I progress with age. There is no discomfort but at times can be very annoying when walking or working out. I've never had an ankle injury in the past. I can make the clicking/popping noise by just shifting my foot up and down. What can I do to reduce of completely stop this clicking/popping.
