about the pain after stretching day

hey guys



i am stretching 3 days per week in taekwondo class , during class i push myself really hard till my pain limit and next day i feel lots of pain on my legs ( fibers or whatever its called i dont know ).



the question is : should i rest the next day of class to let my legs to heal ( cause i try to stretch ) or i just keep stretching till my pain limit again.
