It's always good to get things checked out. Then you know what you really are dealing with. Now you know your hip problem is from fibro. I have that too but it comes and goes. I walk carrying my collapsable cane just in case it gives me problems halfway through my walk. I end up shuffling home. It's a terrible pain.
But, yes, see your gyno. Not all things are caused by fibro. It's better to be safe than sorry.
