Possible Deep Vein Thrombosis?

[Requiescat]

Hi,

I have been having health problems that doctors currently have been unable to diagnose. I suspect that it has something to do with thrombosis. I get cramps and palpitations in my lower legs, even in my feet. Pains in my calf and the back of my knees and sometimes in the lower hamstring. When the sensations are most prominent, and I feel my worst, I feel a strong rushing, as though blood squeezing through the veins in my legs. When I try to stretch them out by bending over and touching my toes my lower legs almost feel like they are vibrating! Rather strange. And my calves - especially the calves - and hamstring are uncharacteristically tight. Does this sound like DVT? I also have shortness of breath and pains in my chest, pains which appear to be at least in part lung related. I had my heart checked and the doctors could find nothing. I have had 4 EKGs, two blood tests and chest x-ray as well as a general checkup by 8 people. But none have taken my concern of thrombosis seriously. Any help very much appreciated.
