  1. 1.Deep Vein Thrombosis

    A strain, commonly called a "pulled muscle," is when a muscle becomes overstretched, and microscopic tears occur. A calf strain happens when one of the muscles on the back of the lower leg is pulled.

    Symptoms should resolve by themselves within weeks to months.

    Rarity:
