Hot baths, stretching and moderate exercise. But the best of all...massages. Honestly, they get rid of all the toxins that are being released, and soothes muscles like nothing else. Your body is adjusting to the exercise, hang in there and you'll push through.
Ahh yeah I really want to go and get a massage, but I haven't gotten around to making an appointment.
I just ignore it. You must become comfortable with being uncomfortable. That's how you grow. Its 100% mental.
