Well I've had a bizarre thing happen. I was tidying my daughters toys on my knees when my ankle cluncked and felt like it needed to click back but wouldn't. The pain was awful and reduced me to tears and frightened my daughter. I was home alone so I managed to get her back in bed-all the time still on my knees and then crawl into my own bed to wait for my husband to come home. I iced it/used heat pack and took analgesia and borrowed crutches to get about then booked to see gp today. 10 mins before the appt it cluncked back to place as I was getting in the car! The gp must have thought I was mad! Its still sore and swollen but is much better. This stupid disease has a way of catching me unaware at times!
