I have been suffering with extreme sciatic nerve pain over the last week (pain all down my left leg). Yesterday I had a magnetic scan thingy (don't know the exact English description for the machine)which has shown up two small hernias in my lower back. I'll be going to the sports doctor / physiotherapist tomorrow so that they can prescribe a series of cures / exercises etc.
Now I'm really worried about not being able to return to running seriously, without even mentioning skiing, rock climbing and mtb.
Anyone out there had a similar problem and been able to resolve it.
Oh, better mention that my age doesn't help - 47.
