This seems to be post waxing folliculitis. Use a antibacterial soap for bath. And apply clindamycin/ fusidic acid lotion on the red bumps. If the area of involvement is more then you would need an oral antibiotic.
Next Steps
Please visit a nearby Qualified Dermatologist ( and not quacks posing as Dermatologists) who could examine you and suggest the best possible treatment.
Health Tips
Avoid waxing over the back and the tummy area. Since the hair shafts are pretty short in these areas and also the hair follicles are distributed in different directions. The haphazard pull during waxing causes more trauma to the follicles and thereby the infection.
