My quad muscle is serverly starined. What is the fastest way to heal this type of injury? I can barley walk right now and I have a baseball tournament in 10 days. I can deal with the pain but my thigh is so weak I would fall down if I apply and real weight to the leg.

If you really want to heal as fast as possible see a therapist. If u can barely walk, that means you really tore a lot tissue. For now keep as much wieght off your leg as possible.

Nutrition is also a huge factor. Eat healthy, drink lots of liquids, lots of protein to build back some of the torn tissue. Carbs are also big to help out those proteins

On your own if you want, follow the PRICE method. Protection Rest Ice Compression Elevation. Check out How Should I Treat a Strained Muscle?
