If you have been using the antibiotic ointment prior to the rash developing, I would stop it.
It is possible you are having a reaction to the ointment.
Also, thank you for clarifying the liquid color, that makes infection less likely. If the bumps appear blister like with clear fluid, it can be a sign of an allergic reaction.
What I would do is apply warm compresses to the area and simply watch it.
If it does not get better with the compresses, mild soap and water then it is going to have to be looked at.
You can also try using an antihistamine
pill (not cream) for itching/allergy like benadryl, zyrtec or claritin.
