I have this swollen bump...
I have this swollen bump outside my right knee. What do you suggest I do? It looked like a pimple but now it's all infected. I've had it for about a week.Could it be molluscus contagiosos? What can happen to me if I don't do anything but apply Polysporin? I would rather not take antibiotics. I had MRSA about a month ago.

Hello I'm Dr Chip

Could you please post a photo for me on this page?

Can you see the picture?

Got it--thanks

No it's not molluscum

You've got an open boil there and it's very likely staph

If you don't get antibiotics for this it will likely only get worse and you may become septic

So I strongly suggest you see your doctor about this

Please let me know if you need any more information

What kind of antibiotics would I be taking?

If I were your doctor I would treat this with either Septra DS or Levaquin

How about Bactrim?

That's the same as Septra--just a different brand name

It's been four days since I've been on antibiotics. The redness has gone away and there's no pain or itching this but there is a little bit of pus still coming out. Can I go swimming in a public swimming pool?

I wouldn't suggest you do that until it's completely healed and not draining anymore

I feel better already! Thank you.

ElanorTracy, CA

Thank you to the Physician who answered my question today. The answer was far more informative than what I got from the Physicians I saw in person for my problem.

You have been more help than you know. I seriously don't know what my sisters situation would be today if you had not gone above and beyond just answering my questions.
