Hello..Thanks for your query
From what you mention, you seem to be having
boils in the area mentioned.This is caused by a bacterial infection.For the treatment :
1)U can clean with Normal Saline 2-3 times a day to keep the area clean.
2) Do not touch it or attempt to drain it yourself.This leads o further infection even after a sense of relief due to
drainage of the pus.
3)Antibiotic creams applied to the skin like
mupirocin twice daily for 10 days.
4) Oral anti inflammatory medicines like Ibuprofen/
Paracetamol may help relieve the pain and reduce the inflammatory process.
5) U might require oral anti biotic therapy to reduce the infection .
To prevent further infection:
-Reduce friction from clothing
-Keep the area clean
Hope this helps..take care..
