Several days ago the upper part of my left hip started hurting when I walk or move. It doesn t hurt when I sit or lay down. The hurt is pretty sharp but not really burning or needles. It doesn t feel like it is necessarily in the joint but maybe above it - perhaps where a muscle or cartilage connect. I have had a hip replacement revision a little over a year ago and walked with canes for a long time, but it seemed that was healed. I don t know what this might be - not related to the surgery as far as I can tell.
