I am having pain in both of my knees

I have knee pains (in both knees), at both the front and the back of the knees. I also get really bad shooting pains in both of them but it's worse in my left knee. I can't sit down for too long, no more than 45 minutes or my knees will seize up and if I walk around for too long they become very painful. I can't win! I'm fine in my sleep, doesn't wake me up at all. Any ideas?

I advise seeing a specialist immediately as knees are very finicky and if a problem goes ignored you could ruin your knees for life.

Instead of asking off the internet, (no offense internet), you should ask a doctor, anyone professional.

Place some warm cloth around it and wait till 20 minutes. This will give you some relief if the problem of your knee is worsen than please visit to your nearest doctor for help.

Its Arthritis . How do I know? My mom has it on her knee and she feels the same signs as you do. Also and this is how I know too because I'm a 14 year old girl suffering from Arthritis. Go see a doctor right away cause it depends on the Arthritis and it can rip one of your cartilages I can't really explain it . But the point is see a doctor soon as possible!
