Jumpers knee and runners knee normally have same symptoms and causes. These are both said to be 'mechnical' injuries - caused by maltracking of patella as GG said. In this case, deep heat and ibrufen will NOT cure anything. They are only dulling the symptoms, while - if you're lucky - the body heals itself.
Strengthening the gluts, vastus medialis and stretching the IT band should help. As to the calf, it could be caused by running differently while you compensate for the sore knee. More stretching would be a safe bet!
