Brief Answer:
Possible normal allergic reaction or beginning of a herpes infection

Detailed Answer:
Hello,

Thank you for using HCM to post your health query.

I saw carefully your pictures.
What I am noticing, seems like a common allergic reaction. I don't see pus, not doesn't seem serious to think of a viral or bacterial infection.

I can not tell for sure though if it is from HIV. Actually in HIV you can get all common reaction, but with an exaggerated effect.

-- If it is not producing pus, then it is not a bacterial infection most probably.
-- If it does burn, and does explode in blisters in 24 hours, means that it may be the beginning of a herpes infection, which may happen in HIV and in that case you may need to take oral treatment.
-- On the other side, if you are taking your HIV medications regulatory it is rare for you to have an reaction because of the low immunity caused by HIV.

These are my thoughts.
If worse or not better, I would recommend seeing a local doctor. If it doesn't have the feeling of burning but only itching you can apply a steroid cream or anti-itch cream, thin layer, but I repeat- only if it doesn't feel like burning.

Hope this is helpful.
Let me know if you need more clarifications.
Otherwise please close and rate the answer.

Regards,
Dr. Papaqako

Brief Answer:
Not typical of an allergic reaction

Detailed Answer:
Hello,

Thank you for the follow up question.

Generally an allergic reaction would itch, and its true that that burning after shave does not count as part of an infection because its normal.

My suggestion would be to not apply anything for now and watch it closely. If worse or not better then consider a follow up here or visit to your local doctor.
I don't think it is a flare up from HIV, but also it is not a typical allergic infection. It may be a viral which may heal by itself in a few days.
Let me know with updated pictures if anything has changed during these two days.

Regards.
