Hi. Thanks for your query. Read and understood your history of pus filled bumps between thighs and underarms. First of all, you need a proper diagnosis, your posting pictures would have helped me a lot to assist you. These look to be hidradenitis from your history. I would advise you the following: Cleaning the affected area daily with liquid povidone iodine. A course of oral antibiotic , metronidazole in low dose, pre and probiotics. Multivitamins, Vitamin A and D in therapeutic dosages. Long term Doxycyclin (you need the prescription for this) Consult a Dermatologist and if the area is small and not amenable to medical management, surgical excision helps to cure the problem. To avoid the recurrence you need to change your lifestyle,. Good sleep and no stress/ anxiety.
