Can't walk

So wednesday I was at the gym with my sister and we had worked out for an hour and then my trainer asked if we wanted to do boot camp. I said yes and drasgged my sister into it. That was the worst mistake EVER! I barely can walk up or down stairs and I can't sit in a chair without it hurting. I used to workout every day and I also used to be a cheerleader and I have never ever been this sore. So with being so sore yesterday, I did not plan on doing any workout what so ever. So I am sitting at home relaxing my sore sore legs and my dog has to go outside. so I get up to let him out and he takes off. I had to chase after him for so long and with my legs being sore i was even more at him. I feel like i walk super weird now especially if im walking fast because it hurts. When I am done being sore im not going to remember how to walk. It will probably be a while before i do bootcamp again...
