Thanks for your question.
I am sorry to hear about your problem.
It is possible you may have developed bacterial infection of your wounds.
A course of antibiotics like Augmentin is required to expedite the healing.
Please keep the wounds clean with peroxide solution daily.
Although the wound healed immediately, you have developed swelling, pain & redness.
This is suggestive of bacterial infection also known as bacterial cellulitis.
This should be taken seriously, as if left untreated the infection spread to the other parts of the body.
Please go to the urgent care for earliest clinical evaluation.
