Can you tell me some more about your problem
Any swelling of the thigh?
Any risk factors for DVT - immobility , recent surgery , long distance travel, previous DVT?
DVT is much more common in the calf than the thigh and when it causes symptoms the main one is swelling.
You can read the link below about DVT.
Worth seeing your own Dr to make an exact diagnosis.
The screen is helpful why did yo have it?
Not sure I can.
Was not able to post your link in chat mode.
I am happy to answer you in this format?
I take you had a -ve doppler of your veins also?
Would usually scan femoral vein , in groin , and popliteal vein behind the knee.
There can be false +ves for d-dimers of course - rheumatoid factor , high lipids etc.
I need to log off for now - almost midnight here - I will check back in with you in the am.
Would seem sensible that you let your own Dr examine your thigh.
