Pimples/bumps formed under bandage, is this bad?

So I burned my self with a soldering iron. No big deal, I put a (large) band aid on it, continue with my business. After about two days it starts to smell, I take it off, wash my arm with soap and water, put another one on. I repeat this process once more, and now, two days after, as I take the bandage off, there are maybe five pimples or things very much like pimple underneath where the bandage was, mostly under the adhesive part. Is this okay? My guess it's from the band aid being on there so long, my pours just got clogged up, but I'd rather play it safe.
