I am having recurrent boils in my thigh and buttock area for past 2/3 months. I am non-diabetic but I have pcod. I went to a dermat and he prescribed me Augmentin Duo 625 thrice for 7 days. It healed but again when i got another boil on the exactly same place that doctor changed my medicine from Augmentin  duo 625 to Linezolid 600 twice daile for 7 days. boil on my inner thigh area got healed but i can feel a small lump remained without any pain and irritation. Then i consulted a doctor in practo and she prescribed me zifi-o cv 200 twice daily for 7 days and hifenac p twice daily for 5 days and mupi 2% ointment topically. As my boil got healed before taking this treatment i was just taking this treatment as a lump remained even after the boil healed completely. So the lump remained as it is now also aftwr completing the treatment. Is this lump not going to flattened ? Or it will remain a swollen scar for longer period? i already consulted so many docs pls give any suggestion.
