I Just Had Left Knee Medial Performal Pigment Reconstruction Tuesday.

I just had left knee medial performal pigment reconstruction Tuesday. My leg and foot are very red and white splotches or something is all over. My foot wasn't like this yesterday and today it tingles. And I also have little bumps all over th3 leg and foot. Should I go to the hospital? I've taken benadryl and other allergy meds thinking it could be hives or some other allergic reaction.
