Really? Well I do know that there is no greater feeling than relief from great pain.
My mom got shingles.
The pain was so bad she was crying and this is one tough lady. Her former doctor told her that the pain would not kill her and she should just endure it. Happily her second doctor prescribed strong pain medicine and, while she slept a lot, the pain was managed. But there are a doctors who are very stingy with the pain killers even for people who are in verifiable pain.
So these people buy it illegally.
Pain hurts worse than anything.
