If the pain gets too bad or you can't cope before August (a long time!) go to emergency. That's what it's for and you shouldn't be desperate, you poor thing! See if the ortho has a wait list to see him before August, and see if you can get put on it (are you available at short notice?).

I used to be an ortho nurse and saw too many people decondition (lose the muscle tone) because they'd put up with it for too long, so don't put off getting pain relief help if you need it. No other advice, but just good luck.
