What can cause severe pain when touched on lower left leg, can feel a knot on my leg when massaged, hurts after running, also have bulging veins on my foot that just appeared since the pain started 8 weeks ago. Pain started when I started training for a 1/2 marathon.
Suspecting a deep venous thromboembolism.Strongly suggest to show it to a local surgeon.Physical test will help making diagnosis.Timely treatment will prevent complications.Regards
