The siatic pain that Rush has can be some of the most intense a human can experience. There was just a recovering addict who has Rush's siatic problem that was on Hugh Hewett - he testified to the differing approaches in rehabbing someone addicted because of pain, and one because of an inability to face life.
Sciatic pain is a mother bear. I have dealt with it for almost 20 years, and never have taken painkillers. I just learned to live with it, because I realized how addictive painkillers were and I refused to be an addict.
I have known a lot of people who innocently enough began taking painkillers and learned that they had bitten into a hydra headed cobra. They ended up being addicted and each facd a long, tough road to recovery. Some lost every single thing they had in the battle
I am not too excited about this. The only thing this confirmed to me was Rush Limbaugh is human, just like the rest of us, and he has faults.
