I finally went to the doctor and he put me on some high dose anti-inflammatory. He felt that I had some pressure on a nerve in my back. He said I could try the pills or he could give me an injection in my back. Again, being the macho man that I am, I went for the pills. When I finished the medication, the situation seemed resolved and I haven't had any more problems. Now I'm back to standing up on Sundays. Ah, better living through chemistry.
