Hi,
Doppler ultrasonography is a good test but also quite subjective. U would need to be seen by a vascular surgeon or intensivist who would look into the complete picture including symps n signs, risk factors etc. There are more tests that can be done and Hamad has got facilities for all of them...If they had any doubt they would have investigated further as doppler is just the prelim.and least invasive of the lot...
So would suggest that u get a consult with an MD and decide ..may just neeed some aspirin!!!
Take care!
