You didn't explained the full symtoms. But it can be Baker's Cyst or Osgood Shletter Disease or any other knee or foot problem. U should go for X-Ray of knee joint and ankle joint first. After that u should go to any expert Physiotherapist in ur area and get properly examined for ur knee and foot. Immediately.
