70,osteoporosis,hip Injury.

I fell hard on my hip 2 1/2 weeks ago on wet tile while walking. (Why in the world did they put a glazed tile insert in the cement of a shopping center?) My bruise and tenderness are on the hip bone above upper leg a couple of inches in back of my side, definitely not on the fatty rear. I do have severe osteoporosis but friends said I would not have been able to walk on it, if it were broken. I was surprised I could walk on it since I break so easy. I have a compression fracture of T11 six months ago that I still have a LOT of pain from, but can't see any difference in my back since the fall. I am over 70. I have not had an x-ray or MRI. My pain is in my hip and groin. It's better in the morning when I get up. When I sit on it for a couple of minutes or more, sometimes it hurts so much, and feels like it really doesn't want to hold me. I am not overweight, have a 2 story house and can do stairs, but it is surely not getting better! Yes, yes, I suppose i need am MRI and maybe my friends could be wrong about not being able to walk on a fracture, especially hairline?
It's so strange to me that the pain varies so much. Sometimes bad, sometimes not so bad. Once I walk the distance of a room or two, it's not as bad. I realize I may have strained my groin in the fall. I realize I shouldn't be so stubborn about going to a doctor, and I have good insurance. Sometimes it seems to be getting worse. Maybe I shouldn't be walking on it anymore than necessary. If I walk on a fracture, could it cause it not to heal? Five years ago I pulled my upper arm apart and the doctor said he was very concerned about it healing since my bones won't hold the pins to put a rod in. Maybe what I need is a kick in the butt: to go to the doctor and get an MRI. Thanks for listening.
