Thanks Everyone, I do feel better today. The endone knocked me out and I had a good sleep last night.
Funny story...
Today I went to a shopping mall with my son. I needed to go down an escalator. I hadn't even thought that this might be a problem. There I was standing at the top of the escalator, wondering how the heck do I get on??? And how will I get off at the bottom???? Bit of a queue behind me now,....it was like 1, 2, 3 step on with the good leg, I'M ON!!!! Then as I got closer to the bottom, a bit of a panic. What if I fall while I'm getting off?? Good leg up ready to go..... I'M OFF!!!! Phew. Who would have thought an escalator would cause a problem. By the end of the trip, I'd been up and down a few and was an old hand.
