Exceptionally creaky knees

[Juicy2020]

Is this something to be worried about, in my mid 30s? Every time I bend down, climb up or down the stairs, creak snap creak snap creak...

Mine do that and I'm 30. I am double jointed so not sure if that contributes. I'm overweight also

Maybe you need more oily fish? Mine creak too though!

Mine made terrible snap crackle pop noises. Discovered my Vitamin D levels were very low. Once that was corrected, no more noisy knees!

Mine creak AND rustle! Always have done. They're really noisy, even my doctor is mildly alarmed but there's nothing actually wrong with them. It's called crepitus - there are lots of different causes but if it isn't painful then generally not a concern. If it is painful as well as noisy then you should definitely get it checked.
