red lesions popping up on left side on back and
Hello and welcome to ask a doctor service. I have viewed the image and gone through the query.
You seem to have furunculosis, which is a bacterial skin infection. I suggest you to take an oral antibiotic e.g either Amoxicillin or Cephalexin for a week. In addition I suggest you to apply an OTC topical antibiotic e.g either Neosporin ointment or Mupirocin 2% ointment, twice daily for a few days. You might need to ask for a prescription for these from your general practitioner.
Hope I have answered your query. Let me know if you need any more assistance.
You need to get a written prescription from a doctor who also has a licence to practice in your country. Anyways, topical Neosporin ointment is available Over the Counter.
