Pain deep in my left calf with swelling. made worse by walking. developed after workout following a lot of sitting around. dvt or related to workout?

Ultrasound needed: DVT unlikely, but ultrasound can tell for sure. A Baker's cyst is also possible and can be seen on ultrasound. A muscle tear can also do this. See a doctor for an exam.

Evaluation Needed: You should see your primary care, urgent care or emergency department soon. It might just be a pulled muscle but with swelling, tests need to be done to rule out DVT. Thanks for trusting HealthTap!
