I had a week full of football and walking. now i have a stiff calf when i walk, what should i do to recover?

Rest: warm compresses, massage and may use OTC medications and mild compression with ACE wrap

Over-use syndrome: This could be an over-use syndrome, a muscle/tendon strain or tear. Seek professional help to determine the severity in case you are making a minor injury worse. Consider non-weight bearing, an ace wrap for compression, elevation, alternating hot/cold treatments.

May have: Strained your one of the muscles that makes up your calf. I would try to do some basic stretching exercises, see: http://www.runnersworld.com/stretching/how-stretch-your-calf-muscles. Otherwise, take it easy over the next week at least, exercise wise. If you develop progressive pain or ankle swelling seek an inperson evaluation.
