<human>: I am a 25 year old male and I've stayed in decent shape for the past few years taking up hobbies such as mountain biking and hiking. As of late, I decided to take it to the next level and get back into running on a regular basis. I've been back at it for 2 weeks and the pain in my knees is borderline extreme. I've been running ~3 miles each workout and I can barely make it on grass now without a potent sense of pain. My leg muscles were sore for a week but that pain has alleviated while the knee pain has basically gotten worse.

At this point, I'm concerned that I am not pushing through the soreness anymore and I may be seriously damaging my knees. Is this pain normal after almost 2 weeks of running after a long hiatus? My right knee was reconstructed years ago, but the pain is equal in both left and right.

Could you distill the essence of the text into 1-3 sentences?
<bot>: I've been running on pavement for two weeks and the pain in my knees is getting worse. Is this normal and will it go away with more running or should I see a doctor?
