I met a woman at a picnic last week who told me that she received botulism (!) shots every three months for her PD symptoms - in her throat for speech problems and in her ankles for joint pain. She was diagnosed more than 15 years ago. I thought I had not understood her correctly (she spoke very softly and with a lot of slur in her voice) but I asked both her caregiver and her husband who confirmed that this was one of the treatments she was receiving. Anybody know anything about this? I find it hard to believe, but........ Nancy Shlaes deGrazia
