So, the leg is a red herring

The doctor today confirmed that the actual problem is in my lower back, but beause of the nerves invoved the pain is 'referred' to my thighs. Both of them, as confirmed by the fact that the other one started acting up during the drive home.

Time for a new office chair at 'work', and an attempt to break some other bad posture habits. The chair at home needs replaced as well, based on what I've learnt today, but it can probably wait.

This afternoon I looked at chairs ranging from ~$280 to $1800+ I tink I might buy one in the $300-$400 range for now and upgrade later.
