Broken hip, maybe a pulled muscle, what is it?

The answer to that depends entirely on the cirstances. How old are you, and how did you break your right hip? Hip fractures are almost unheard of in people under 50, unless there is serious trauma involved, and "growing too fast" is a ridiculous explanation ( I'm an RN who works medicine, pediatrics, and ER, by the way). And what makes you think that you broke your other hip - there are thousands of reasons why it would hurt. If you are truly concerned, ask your doctor for an Xray, just for your piece of mind. If it shows nothing, ask for a referral to a physical therapist or licensed mage therapist.
