I CANT straighten my leg?!

I think i pulled a muscle in my right leg. I was working on my car this past weekend bending down. but my left leg doesn't hurt. I started to have pain in my knee but now my knee only hurts when i try to straighten it. it feels just fine when im sitting and have it bent in ((indian style)) when i stand i start limping because it hurts to put pressure on it. that's when it hurts so bad in my lower calf. So i think i pulled my calf muscle. but i don't know what i can take, or what should i do to be able to talk normally again. I hate going to the hospital because they take so long, and i don't know what they would even do for my situation. so please if you have advice, i;d love to hear. thank you!Health Question & Answer
