I had a microneedling appointment on Wednesday for stretch marks. I think I'm infected? (Photo)

I had the microneedling procedure done and two days later doctor called me in an antibiotic and and anti nausea Medication. I had a low fever of 100.5 and burning sensation on my stomach. I was told to put bacitration on the phone kind but when I put the ointment on I feel it's worse. Should I let it air dry or what should I do? This was a step I was doing to avoid a tummy tuck but I may have just scarred myself much worse.
