If there is pus inside it, it need to be taken out by simple surgery. It needs to be seen if its big enough with pus or not! If small or already bursted, then can apply ointment Mupirocin for two times a day for seven days! If the pain is more serious with fever and swelling is big please visit the hospital nearby emergency and have the pus drained out!

Thank you for the reply. The problem is with my wife, 38 yrs old. Yes, it's very painful, and was having a fever of 100 two days back. Since then, having Flexon twice a day. It looks like pimple with pus and redness around it. It numbers more than a dozen. Here how it looks like (please follow the link below). https://www.verywellhealth.com/thmb/_r1Tv9AGFAK0u-nRzcVFJBlTkK0=/700x0/filters:no_upscale():max_bytes(150000):strip_icc():format(webp)/close-up-of-a-boil-680793359-5bfd9478c9e77c0026f6c816-acda0756f838458c907779fa5aa47d0d.jpg Thanks again!

Is it painful and pus seen? Do you have fever? What is the size of the lesion? Need to see the photo before deciding what is it. Follow the link to have online consult with skin expert: https://www.hamrodoctor.com/doctor/dr-anil-kumar-bhatta
