What Causes Pressure Sensation In The Neck Area?

I have a pressure sensation in my neck, it is on both sides. When I bend over, the pressure in my neck and head increases. I do not have headaches, my BP is stable on Doxizosin and Carvedilol BID. I have a history of Lupus Anticoagulant and have had a pulmonary embolism about 10 yrs ago. I am on Warfarin for lifetime. My questions is what kind of physician to start with. My concern is pulmonary hypertension- I need to find a new primary - long story but I used to work for my primary care MD and sometimes I feel too much of my apt time is spent just chit chatting and my concerns not addressed. My rheumatologist is ok-but not a real easy person to talk to. I also have been feeling a little short of breath and very tired- but I attribute that to being overweight, out of shape and I work about 55 hours a week. I know, I am a mess!
