A few residual knots and twinges, but I was back to walking yesterday, and the pain is rapidly decreasing. Am going to stay on the new diet, however; but I've allowed myself a bag of Snakes every couple of days, as I love these, and don't want to become completely sadomasochistic. They don't seem to be doing me too much harm.
I want to thank everyone who made comments wishing me a speedy recovery; it was very much appreciated, as were the suggestions for treatment.
Now, back to the forum! ;-)
