Thanks everyone!
Maeve , The head of my femur was sticking out of the edge of the socket too, I'm able to understand why I stood crooked, even as a child. In later years it been because of the pain too. I hope you have as good a report in four weeks time. I've never given surfing a go, but do love to body board. Although I find increasingly I'm not interested in going into the water, unless its the hot pools! We have natural thermal pools just north of where I am, so lovely to go and have a soak. I find the sea too cold most days, even in summer. I'll have to go next summer, just to scare everyone off the beach with my scar.

I'm sure your tea bag action will be fine. The surgeon didn't mention the 90 degree rule, but the physio has advised when bending past 90 degrees, to turn the leg outwards, this puts the hip into a more secure position. (Not like rolling a straight leg to the side, but say when sitting, sit with legs apart and knee and foot turned out, then bend down or raise foot.). An overseas trip how exciting, where are you going?
Kim22, No, I'm not worried about any of the "don't do's", I'm not planning on taking up skydiving, or marathon running anytime soon.

I hope you are feeling better soon.
nerdgrrl , I think it's more the danger of drowning if you dislocate in the water, so little waves might be ok, I'm not sure. There's more risk of dislocating if you fall off from five feet above the seabed and then get pounded onto the sand below. My next appointment is at the one year mark, in 9 months time. My goodness that doesn't seem very far away.
zauberflöte, wishing you a good recovery too. It's not been plain sailing, but I would have to say its been quite good so far.
