I hurt my right knee. Ankle and foot is swollen and sharp pain in knee, calf, and ankle when I walk. What should I do. I tried ice and heat for 2 days?

See your Doctor. Knee injuries are painful. See your doctor for examination and appropriate treatment.
Seek medical help. If pain and swelling not resolving should see an orthopedic or family physician to determine strutural damage such as ligament, meniscus or bone. This usually will require imaging, the tests determined by clinical suspicion of the physician.

I had an ankle injury, which has gotten worse and it hurts to walk, and now my knee on the same leg is hurting. Could the knee pain be b/c the ankle?

Yes. The mechanics of walking are off with an injured ankle. It would be easy to also injure the knee in that way. Time to see a physician, xray if indicated, maybe a walking cast, at least compression bandage, crutches to take some of the weight off the leg if no walking cast perhaps, ice, rest, elevation. Exercise via swimming for now. Read more...
