Yes, that's something I thought could be the cause as the tingling started near the end of the chiro. Most of the chiro was massages rather than pop the neck though that component was there. I only started getting better after physio where I started strengthening my neck. Though the chiro helped me greatly in reducing other symptoms.

When my head gets really bad usually the only thing that helps other than icing is nortriptyline, which usually stops the symptoms within 10-15 minutes, i'm not sure if that helps with increasing blood flow but it pretty much stops the tingling. Thanks for your replies.
