MED PRIDE Silver Calcium Alginate Wound Dressing 4"X5" Pads Non-Stick Highly Absorbent 10-Pack

Q: I find it stings when using. Is it because of the silver, like silver nitrate used in cauterizing?

I don't find that it stings me but I now use them over Adaptic guaze because Silver calcium alginate wound dressing pads on the bare wound would pull off the skin from the sides of the wound.

Q: Does it have oil in it?

I don't believe so. It's a seaweed based material with silver in it. It's not oily to the touch. I'm not sure if you're worried about texture or allergies. There shouldn't be a problem with either.
