Andrea,
I'm no Jen, but I'll try to pitch in here if I can. I know Jen is swamped right now planning her wedding. She only has a few days left and I doubt she's got much time to be around here much right now.
I think it is highly unlikely that your pain is from osteoarthritis of an onset from your recent fall. Osteoarthritis is a condition that occurs over an extended period of time. It sounds to me more like you're still having pain from a contusion sustained in your fall. I know that the description you typed from the internet sounds exactly like what you have, but you really can't take everything you read on the internet to heart. Although, I'm sure you probably do have some osteoarthritis in your hip. I'm sure I do to, it's a natural occurrence of aging. It happens to all of us. The difference between what causes us pain is the degree of severity. I'm sure you could probably find several other articles that describe other conditions that would also describe what you are feeling and would sound like what you're suffering from, but that doesn't mean you have those either. Be careful about self-diagnosing is all I'm trying to say. I'm just thinking that your continuing pain is probably from deep bruise you likely suffered in your fall. I fell out on the deck the first part of September and landed on my left knee. I fell really, really hard and that thing is still bothering me. I know I had to bruise it really deep, if not fracture a bone. I probably also set it up to get osteoarthritis in it faster than I normally would have too. But I'll wait and let x-rays and the doctor tell me that. Right now, I'm thinking the pain is still from the fall. Probably with you too this soon afterwards.
