Hi,
Welcome and thanks for posting your query to HealthcareMagic.
As per your query you have red knots on body which are Itchy, sore, pus-filled bump.
The characteristic feature appears to be problem
folliculitis. This is a common problem due to simple infection in the skin causing redness and pus.
You have not told your age and the time since the problem is present. Even then go for blood sugar check up. I fit is normal then there is nothing to be worried. You can take a course of antibiotic such as
ciprofloxacin or
cefadroxil for 5 days along with pain killers.
Do not scratch or even try to touch the area unnecessarily, apply any antibacterial cream such as fucidin or
mupirocin or
gentamicin 2 times a day in a very thin layer so that it should not be visible to naked eye.
I hope these information's will help you. If you have further queries I will be happy to help.
"Wish you good health"
Regards,
Dr Sanjay Kumar Kanodia
