Headaches...still?.....again?????
Doug, Good to hear the neck arteries are good, but be sure to NOT let up on the Doc's they will rule this and that out but if you stop, they will and then thats when bad **** happens!
Keep us informed I too have the Neck Sono done right about the time they found I have a 30% blocked artery in my left leg so...
Prayers are with you man!
