Ive had on and off leg pain for about 2 months. sometimes its in the back of thigh hamstring area then i feel it in my calf its like a twinge feeling no swelling or discoloration and the pain in very mild. what could this be?

Leg pain: More than likely these are muscular symptoms, perhaps related to some degree of tightness and not characteristic of phlebitis. Lack of tenderness,leg swelling or pedal edema are all reassuring. If you still have concerns, consult your physician or a vascular surgeon for evaluation and advice.

Leg pain : Your leg pain can be several things. Lumbar radiculopathy, lumbar canal stenosis, mineral issues, circulation issues. I think based on the limited information that lumbar radiculopathy is more likely. See a doctor in person who will have a better chance of providing you the correct diagnois
