Red Rash On Inner Thigh, Itchy, No Flaking Or Oozing Fluid. History Of Lyme Disease

I developed a circular red rash on my right inner thigh. It had a red dot in the center. I was treated for Lyme disease with an antibiotic for 14 days. Since, I have now developed the same appearing circular rash under both arms, not in the armpit area but just above it. I have at least 4 lesions under each arm. I have been given a topical ointment 6 days ago, am using it as prescribed. No significant change in current lesions. I now am developing more lesions on my left inner thigh, more also on the right. They are slightly itchy, no flaking or oozing of fluid.
