Hi, I seem to have had bumps on my groin, chest, and armpits, and they moderately big. I have had anal sex, we are both hiv negative, is this a sign?

Hi, I seem to have had bumps on my groin, chest, and armpits, and they moderately big. I have had anal sex, we are both hiv negative, is this a sign?

Have an exam ASAP: HIV is not the only STD infection you can contract and what you describe could be enlarged lymph glands which could mean some sort of infection - not necessarily related to sex. But any sex is better if you play it safe! We need to start to see it that way. Worried folk are less attractive - sick folk even more - it's a fact! Always use a condom! For these bumps, have a simple exam & lab work. ...Read more

Likely staph: Unfortunately you sound like you are likely carrying staph. This will often occupy the moist mucus laden areas inside your nose & contaminate your fingers when you touch your face/nose.

Contact allergy: You may be allergic to something in your bra and the metal in the bra hook. You may try a different make of bra and one with a plastic hook. Wash the bra thoroughly before use. See that your bra is not too tight.

It takes a few days for the spasm to dissipate. There are time when swelling develops, like any injury. Icing the area usually helps reduce the swelling.
