Squats will make your thighs and but appear stronger because they make the muscles in those areas stronger.
You probably haven't been using those muscles that you don't use a hole lot of. You just need to keep doing your squats to build up those muscles so then after you do your squats... they won't hurt. Trust me... my arm is really sore from softball pitching... it's just because i haven't been using those muscles for awhile and i need to strengthen those muscles :D
