I have about a 2 inch lump in my neck for about 6 months now. I had a CT for "swollen glands" and it showed that my carotid body was enlarged. My blood pressure has no gone up to about 134/89 fairly regularly. (It used to be 100/80 for the majority of my life) I am getting major pulsating headaches, dizzy spells, ear and jaw pain. I also have had bouts of swollen joints (usually my hands and feet). My feet are swollen most days. They have started me on HTCZ but that doesn't seem to be lowering my blood pressure. The lump does pulsate in my neck. I am also starting to get tingling feelings near my left eye and onto the side of my head. I am negative for CMV, EBV, HIV, Lyme. My red count is hovering just above normal low. (usually about 4.0) My sed rate is between 20 and 28. My CRP has been elevated for 6 months. My ANA is negative as well. Do you have any suggestions as to what could be going on?
