In March 2012, I fell out of bed and fell hip first onto the concrete floor. For one month three was extreme pain from my hip to my knee and then my ankle. Every so often I would get this popping feeling on my back where there is a bone that pops up/out before you reach the butt. It feels sort of like a discolcation but when my doctor checked he couldnt pin point what it is. Just like the popping there would be pain most of the time its in my knee sometimes my ankle but barely my hip. I didn't see a doctor about it until March 2013. I still have all these and im unsure what to do. Should I see a specialist of so e sort. This becomes bothersome when working or doing routine things.
