I wonder what he's feeling. The blockages are usually low in the jugular, near where it meets the subclavian, at the base of the neck or essentially in the chest. My guess is that your doctor was pressing on the jugulars further up. He may have noticed a size difference between the two jugulars, but size differences are common among the healthy controls, with the right jugular typically the larger of the two. All that said, we've heard from people with lyme with CCSVI blockages before. A theory is that the blockages create venous congestion and through various effects on the endothelium, adhesion molecules are increased which open up the blood brain barrier, which allows the lyme bacterium to get a foothold in and go neurological.Anyway, my lyme doctor thinks I have inflammation or a blockage in my right jugular just by pressing on it and comparing it to the left jugular.
