Bugger about the shoes! You'd expect them to last a bit longer than that. Are you going to get them replaced with the same things?
I'd love to avoid pain killers altogether, given my chronic pain it's not going to happen though. Just watching 'is modern medicine killing you', and there is a young guy with back problems. Dr has recommended a high protein lower carb diet among other things. Interesting, but I wish it was as easy as just making some dietary changes.
