question: My 10 year old son is having pain beginning in his groin area and down his leg...all on the left side. It is extremely painful and hurts when moving the leg or putting weight on it. Monday, this leg started suddenly giving out on him and hurting some what. But when he woke up this morning, it was alot worse and has nto gotten better all day long. I have given Ibuprofen adn he has stayed off of it all day. What could this be? Is it somethign that will go away with time? Should I make him go to school, or take him to the doctor? He cannot walk unless holding onto something and even then it s with a limp and very slowly.
