Bad knee pain after cycling
I recently bought a bike and began riding. I loved it so much that I went out a couple times and rode for close to 2 hrs. Afterward my knees were killing me! Could this be arthritis, or something else? Did I just overdo it? I know I have osteoarthritis in my lower back, but my knees are usually fine. It never hurts to walk long distances, or even jog. It just seems to hurt when I bend my knees, such as cycling or walking up or down stairs.
My last cycling adventure was 10 days ago, and I'm still having some pain when I bend my knees (not severe, but there nonetheless). I've been sporadically taking advil and tylenol. Should I continue to take these? It seems like the pain should be gone by now.
