Hi all wondered if anyone can offer advice? I've been diagnosed with sciatica and a herniated disc and so have been told not to run by the gp. However I'm getting different info from others. Some say walking and running is fine and actually, when I do run, it does not actually hurt and I make sure I warm up and do lots of stretching after.Is there anyone who suffers with this or can offer advice? I'm missing my running and Im hoping to still do the great north in sept.
