Hi David, I have had a long history of neck pain. Although I think it resembles Tortacollis in that I've had the pull to the left since the early 1980s, I now think it may have been caused initially by undiagnosed whiplash complicated by repetitive strain injuries and possible nerve damage. I reached this conclusion through discussions on some other aol forums & reflection on my own history. A member of the neurological staff which oversees my neuro care evaluated me for Botox treatment in the past year, & concluded it would be risky in my case. Thanks for your thoughtful response, & may we all have the best possible New Year. Regards, Barbara Blake-Krebs [log in to unmask] Merriam, KS
