main points to remember:
*always keep your knees together - do not do any lung or wide leg type movements, including when getting into a car
* don't roll over in bed, roll under
* get chiro or osteo help. I see a chiro twice a week and will start physio next week
* rest. Do not push through or overdo it - you pay for it
* accept. Yes, you walk like a nana and that's frustrating. You feel like you can't do things or plan your life. This is just the way it is. It's better to plan for no more than 30min walking a day and accomplish it than plan for more and not make it, as we'll as ending up in agony
* online shopping. 10min in a supermarket can end with me in agony. We've switched to online. A bonus is we're saving money, even with the delivery fee, simply because I'm not impulse buying as I walk down aisles.

With DS1, I ended up on crutches and had a temporary disability parking sticker for my car. Old ladies would help me by opening doors or carrying bags. I'm hoping to stay off crutches as long as I can this time, hence the 2 x weekly chiro. Affording it is another problem.
