Currently, I can stand for about 20 minutes before I get lower back pain, and I can sit for about 10 mins before I get leg cramps, pins and needles. Chiropractor said lying down is best - I pointed out that lying down in pubs might lead to being thrown out! :(
Learning to handknit whilst reclined at the moment. It's not really conducive to machine knitting. Might try and get some reusable cool packs - apparently TENS is not an option.
Thoroughly fed up with this stage, it can't heal soon enough! The knee chair at work is actually blessed relief! Otherwise I suspect I would be off work!
