Hi There, Researching A Blister Forming On A 31 Day

Hi there,
Researching a blister forming on a 31 day old knee scar. I fell down stairs onto concrete and grazed my left knee which always takes the impact if I ever fall. The scar healed well but the impact has left my knee a bit stiff and sore to kneel on.
I had CPR renew class and took a hand towel to cushion my knee but noticed a blister had formed over my scar immediately after floor demo.
I wrapped my knee overnight but the mixed pink plasma blister remained intact. Looks clean and healthy enough but should I wait for it to reabsorb & heal or drain , disinfect and cover?
I have not seen a doctor re this as fall happened over holidays and was able to rest, and care for wound.
