Detailed Answer:

Thank you for the query.

Can you please attach a photo of it? It would be much easier to give precise answer.
Redness usually indicates an inflammation. The red area should be also swollen and painful in case of inflammation.
Such inflammation can be caused by several things including bacterial infection (erysipelas), veins thrombosis, impeded veins flow due to changes in armpit lymph nodes (breast cancer), allergic reaction (caused by some bug bite for example).
Most of mentioned reasons need medical attention and proper treatment. That is why waiting is not a good idea. Please consult your doctor.

Hope this will help. Feel free to ask further questions.

I have a probable bug bite between two toes, which seems to have begun to be infected (I think I scratched it in my sleep). I cleaned the area and applied mupirocin (3x/day, this is second day). It doesn't seem to be getting worse, but isn't much...

Hi, I m writing this to ask if you think I should go to the ER. I have a bug bite that I believe to be a spider bite on my inner bicep of my right arm. The actual bite was very swollen and looked like a bullseye. The surrounding area almost covering my whole bicep has broken out in what looks like little red dots and I believe they are broken blood vessels. There appears to be a red streak forming down my arm, a little past my inner elbow at this point and it s starting to worry me. I don t have a fever, but the whole area is very hot to the touch. I really need some advice, I have been icing it and it seems to be reducing the swelling, but the line has not gone away and neither has the red dots and the area is still very warm, even after having ice applied for a good amount of time now.

About two days ago I got a bug bite and dismissed it as a mosquito bite. Well now it's swelled to about two inches in diameter, is warm to the touch, and when I accidentally squeezed it, it oozed a thick brown liquid with some blood. Now it's more of a clearish amber, but when I looked this up all I got was Brown Recluse. I don't really feel sick, so what could it be?

my husband woke up with a bug bite on his bottom. It felt like a mosquito bite, itches, and formed a lump like a mosquito bite, only the lump continued to spread. It's about the size of a half dollar now and has become painful. Any ideas of what it may be?
