Lately my knees are constantly weak.?

Question

For the last 4 nights, every time I go to bed I have difficulty going to sleep cause my legs feel weak, kinda like growing pains. Always feels like I need to stretch. I'm 20, and stopped growing years ago. It's so uncomfortable. Why is this?

I have this on a regular bases, but it's just been every night lately. =S

Answer 1

It's odd that you say your knees are week because your knees don't have ANY muscle.

Tendons, ligaments, 3 different bones, miniscus... sure. But no muscle.

Are you sure you don't mean your thighs, hamstrings, hips, and/or calves are weak?

PS: Could be something serious like MS or GBS. Could be something minor like you're dehydrated.  

Answer 2

It could be nerves or even Restless leg syndrome see a doctor so you can know for sure.Oh and get a pillow and sleep with it between your knees that might help.Have you been eating right

it might be your low on potassium my friend said.Or maybe you have been sitting too much.
