Any ideas before I take myself to the doctors 
I'm putting off going as I know they will blame my weight and also I can't go until my next day off work
Knees always been fine. I was exercising and had a twinge in my right knee, so had a break for a couple of days. Woke up and both knees were throbbing like toothache type pain
Bending them so sitting down is the worst, and it wakes me up at night. On a medication that can cause joint pain apparently but I've been on it 2 years with no issues
The only thing that helps is naproxen and they pretty much hurt 24/7, standing and walking gently is ok but trying to sit down is... fun 
I'm 39
