Hi doctor, I recently had a stiff, cold knee and swelling of my legs and ankles, a little bit of pain in my knees and elbows.

The symptoms suggest that there's a joint defibrillation, which can cause fluid buildup in the joint sac, causing stiffness, swelling and pain around the joint.
Doctor, I've had terrible headaches in the last few days.
The symptoms seem to indicate that you're suffering from migraine.
