Your body definitely could be. Is the area around your incision warmer than skin higher up? If so it could be an allergic reaction that could cause infection.

@santistevanmommie, it don't have a scent. it's just really itchy & looks swollen and red. I'm not sure if my body has a reaction to the glue on the strips.

Does it smell?? It could be an infection but typically when it's an infection it's like puss. Definitely talk to your dr about it
