How Long Does The Pulled Muscle In Thigh Take To Heal?

I started doing a boot camp exercise class. Keep in mind that I had not done any kind of physical exercise for past 8 months prior to starting this class. I just started the class last Monday....attended 3 classes last week so was very sore!! Last Friday, I slipped on the ice and I'm pretty sure I pulled the thigh muscle in my left leg. How long do I need to miss my boot camp class to allow for this to heal properly? I can barely do a squat but it really burns in my thigh area when I do.
Thank you
