For about the past week or two i've had intermittent pain in my left calf. it happens while sitting for long times for work and persists for an hour or so after getting up. the last two days it is more constant. no injuries and my right leg is fine.

Probably not DVT: DVT symptoms include calf pain, unilateral swelling, redness, warmth and a heavy achy feeling. Ultrasound is the most common diagnostic tool, but the dr can also order a d-dimer or a venogram. Other explanations for the pain include muscle injury/overuse, tendon inflammation, infection, lack of movement or exercise. Try standing up at least every half hour. Stretch leg straight bring toes back.
