I finally went to see the physiotherapist about the annoying discomfort/pain that I'd been experiencing in my right leg, and now left knee. Turns out the root of the problem is likely sciatica and all the rest of the aches are stemming from that. That makes me feel old - sciatica is something great aunts experience, surely?!
So my lower back has duly been prodded and poked to try to loosen it up, and I have been sent away with stretches and excercises to complete every 2-3 hours. They will take some explaining to my office-mate. Also my cat, who tried to 'help' with my stretches earlier. She was most indignant when I tried to explain that a cat on the small of my back mid-stretch was probably not part of the prescribed exercise.
And no running allowed , so vicarious running for me for at least a couple of weeks - please keep posting guys! I'm going to need to imagine I'm running along with you until I can get out there again myself...
