Yes... ICE, ICE, ICE!!!!! Reducing any inflammation is key to recovery. They have recently come out with cold packs that are made with clay (so they never freeze solid) so they can wrap around you leg so you can continue light daily activity. They are available at any pharmacy, Walmart, and Target for around $10. After a few days of icing with minimal exercise you want to start in with easy stretching and with the exercises in the video Jami posted. Luckily is sounds like a minor strain as hamstrings are PAINFUL so just icing and easy movements are the way to go. This is a good time to work that putting and your standing midrange game
