I can't make my legs straight?

Question

How do I fix this? e.g. When I sit down against a wall and put my legs forward, they are never straight, they are always bent. It hurts really bad if I try to make them straight? Any ideas on how to fix this or am I stuck like this my whole life?

Try slowly stretching them out, your muscles might be tight.  You should also talk to your doctor if it bothers you too much.
