I have had a dvt in right leg 1yr.ago diag w/ factor 5 laiden.3 days now with pain in upper right calf , er ddimer 6 doppler shows good flow ?

Reassuring: Given history of factor v leiden and prior dvt, it is important to take leg pains seriously. Ultrasound with doppler is very good at detecting even small blood clots in the calf and thigh. Given your lab and doppler findings, doubtful your pain is coming from a new dvt. The symptoms may be musculoskeletal or could possibly be related to superficial veins (though they should have checked on us).
