It's the short lived part about blocks that worries me. I know I have read that they are short lived somewhere else as well. I realize that everyone responds differently to these treatments but if all I can get out of it is a few hours, than is it worth taking the chance of a spread? Form what I have heard so far, I am still unsure of the effectiveness of the blocks. Guess I can get the opinion of my other PM doctors. I see one on the 29th of this month and another on the 13th of October. I will see what they have to say as well.
