@Belladonna Is the doctor doing your procedure the end of this month the same one that ordered the bone scan? I agree with Mojo that this answer was not helpful but it could have been a dreadful diagnosis, too. (which is my way of trying to say there must be a positive side to this

I think you need to get on the phone first thing Monday morning and call your doctor and tell them you are in excruciating pain and you need to find out what is wrong right now!! If I am reading your posts correctly, this pain is not coming from the hip you are getting worked on July 31 so that procedure will not help this pain at all.
You do need to try and find something positive to think about. And don't try to do things around the house. If moving causes pain, just stay put and read, watch tv, knit, post on BS, play games on your phone or Ipad or whatever you do to pass the time. Then Monday morning as soon as the doctor's office opens, call them and see if you can get some answers.
In the meantime, we are all here on BS to help support you so cry, rant, whatever helps and we will all listen and offer what we can to help. Hang in there!!
