A few questions.
1) How long have you been walking before you took up running?
2) Are you strength training?
3) Have you seen your doctor?
4) How much are you running (for how long, how many days a week?)
5) When are your rest days?
Pain that persists more than a couple of days is a sign something is wrong. Only a doctor can provide adequate guidance on pain relief, because causes of pain can differ. What may be hurting your knees may not be your knees, but improperly fitted shoes (yes, even if you get fitted, there's a lot of room for error... especially if you're inexperienced in telling what a good fit is for yourself.), poor form, overtraining, and other underlying injuries can be at fault.
