@Sparkly, you'd be surprised at how many people are in this same position. Hips can deteriorate very fast sometimes. Knees too, but we see it more with hips. People sometimes try to hold off their surgery and end up hurting or other times it just plain speeds along and they are in pain. The main thing you need to do is keep your spirits up because help will be there very soon.
Talk to your surgeon on the 2nd about what you can do to help with the pain in these last weeks. Some doctors don't like you taking pain medication because, for some people, that may reduce its effectiveness post-op. But, if you're in significant pain, that may outweigh everything else and you might be able to take them for a while.
Your surgeon will have seen your latest xrays (hopefully he'll take new ones on July 2) and knows for sure how deteriorated your hip is. If it's bad enough, he may insist on minimal movement so you do not risk further damage.
Try not to worry about your muscles. They can come back. While you're in bed, there are exercises you can do to keep some engagement of the muscles. And you're probably getting up and moving about the house a little during the day and night. That helps too.
This is a time to be really good to yourself. Rest, ice and take something for pain....Tylenol at a minimum (1000mg every 6 hours, whether you hurt or not so there is always medicine in your system. Make sure you don't go over 4000mg in any 24 hours period and count all medications with acetaminophen like cold and sinus medicine). Ice the areas that hurt (put a towel between the ice source and your skin so you don't damage your skin). Take advantage of any opportunity to use a wheelchair, elevators instead of stairs, or anything that lessens the pain for you. Try to distract yourself as much as possible with things like your crafts and television. Maybe have some friends come over and bring lunch for a visit. Read. Napping is okay.
Best of luck to you and remember we're here for you!
