Oh Alpha, the day is over and I never get to this site until after hours. I hope you made it through your day. Yes, of course sit if that's the position that alleviates the pain! I've had sciatic problems in the past and it's so painful but my doctor said ice, then heat, then repeat, I seem to remember 5-10 minutes each. I take good old aspirin for an anti-inflammatory because my stomach can handle it.
