I tried the pyrads system on blogger.com. I got 8,000 impressions free with my blogger pro signup. Based on the results, I am very glad it was free, so I am not pissed off about wasting money.
They did run my ad for 23,000 impressions over 16 hours today, though. I got a whopping 11 clicks (0.04%). Now I will grant you my tag line on the ad was not the greatest ("Commentary presented with laughter and love."), but only 11 clicks! 23,000 impressions has a street value of just under $30. If I am going to pay over $2 per visitor, I at least want people to leave some comments!
I think pyra will have to do some reworking of the pricing structure on this one. Are any of you using the pyrads? Did you have better luck?

I have found it helpful to do the stretching exercises my physical therapist recommends. Do some core strengthening exercises, such as the ones highlighted at The Mayo Clinic. By keeping your core strong, your back won't put itself in a position to cause that sciatica pain you are having.
