Has anyone tried epi Kool pads? Do you recommend it and why so? Where can I get them?

I was prescribed to it after delivery at TMC. I recall there are 3 epi-kool pads in a box.. However, I personally find it too thick & there’s no wing to secure it from moving.. but it did help numb the pain esp during the first two days after natural delivery. Once I’m back home, I used Sofy’s Cooling Fresh pads which gave me the cooling effect too & sure does help make the wound feel a lil less uncomfy. There are large maxi sizes.. :)
