Recent i've started jogging for the first time in years. On the very first day, i've jogged about 3-4 kms after stretching. But later on that day my calf muscles started paining. I feel pain while walking so I applied some fast relief and ice pack on my muscles but the pain didn't go. I didn't go for jogging after that due to pain. It's been 3 days. Should I start jogging gradually to get rid of the pain or how long should I wait for the pain to go.
