You need imaging: You should see your doctor. Given your history, you need to be evaluated with an ultrasound and possible more imaging. First thing would be a physical exam to see if there is anything obvious.

Groin pain: It is important to get a Duplex vein scan but this rarely shows anything above the groin. In thin patients, the iliac veins may be visualized. Duplex waveform analysis of the common femoral veins may suggest if there is iliac vein obstruction. b mode component of ultrasound will also show if there are lymph nodes in the groin. An in person exam will determine if there are hernias in the groin.
