Take rest. Do hot fermentation and calf stretching exercises

• Stretch Calves • Get a custom made insole. • Hams Stretching. • Sports Taping. • Contrast bath---It is a form of treatment where a limb or the entire body is immersed in warm water followed by the immediate immersion of the limb or body in ice water. This procedure is repeated several times, alternating hot and cold. Note that the treatment should always end in the ice water, as heat will induce the body's inflammatory response, while cold helps to decrease inflammation.

As per history given, it seems you have developed DOMS( delayed onset muscle soarness). First of all put ice packs and stretch your calf muscles every four hourly.

It will settle down in three days. Drink plenty of water. Do stretching exercises. Consult ortho if not improving
