Is it normal that my knee's click?

My knees are constantly clicking when i crouch down, and not faintly but LOUDLY! Plus, when i walk up the stairs and run they hurt!
WE KNEE CLICKERS NEED HELP!

DUDE! When I climb the stairs sometimes it's like "click,click,click,click,click,click,click" (etc)... I wouldn't worry about it.

Mine click loudly every single time i crouch down but not when i walk up stairs or anything and they dont hurt :/

Mine do the same thinggg(: lol

Nope. Not normal. I recommend amputation.

I have a disease in both of my knees called Osgood Schlotters Disease. I can walk. I can still run but i face the concequences of pain afterwards. This makes my knees click ALOT! it's normal

It cod be that you're fat or that your diet is bad. Excess weight will cause this as well as poor diet. Eat fish fish fish and more fish. The of in fish will do wonders for you. Salmon, sardines and cod are good. You'll thank me in a couple of months.

I used to have this problem when I was effectively anorexic. I was losing a lot of muscle mass and my knees started clicking. After some research I found that weak leg muscles were a possible cause, and after I got my appetite back it stopped.

It will lead to arthritis and you gonna suffer the pains of hell.Get ready for the pain.

Mine click as well. I think it's normal. I have no idea what the long term consequences are.
