The dopplers ultrasound on right epidytmis just shows red colour scale not the red and blue scale tougher. Does that mean that mean that the ultrasound technician might have forgotten to check the verecocele on this side .However she was able to diagonose a very small verecocele on left side which actually shows red and blue scale together. I have more pain on right side of testicles.

Ultrasound is a sensitive and accurate technique for the evaluation of testicular abnormalities, and is widely accepted as the first-line imaging technique for many common and uncommon testicular diseases.
Ultrasound specially Doppler need to be done by experienced ultrasonologist. Dynamic information such as blood flow can be added to the signal by using a physics principle known as the Doppler effect. The Doppler signals, which are superimposed on real-time gray scale images, are extremely bright in black and white images and may be color coded to reveal the rate, frequency shift and direction of blood circulation, phase shift as well as the amount of vascularity of an organ.
Flow in one direction is created red as well as in the opposite direction, blue. The colour tone and intensity of color can correlate with the velocity of flow. Thus, generally, venous and arterial flow can be depicted by assuming that flow in these 2 kinds of blood vessels is parallel, but in opposite directions. Since portions of arteries might be tortuous, modifying orientation towards the probe, different colors are displayed within the same vessel even if the true direction of blood circulation in that vessel has not changed. Thus, an analysis of flow characteristics requires careful observations and cautious interpretations. The absence of flow in a fluid-filled structure can differentiate a cystic structure and a circulation system.
Ultrasound sometime is effectively the sole scrotal imaging technique that a patient will undergo prior to surgery. Traditionally, Bmode ultrasound is extremely sensitive in the detection of testicular masses, but does not provide histological diagnosis.
So in your case please ask your doctor who has done the ultrasound and he can give you a confirmed report.
