Thanks for your query.
It looks like you are suffering from folliculitis
and hence doxycycline was prescribed.This is most frequently caused by a bacteria called Staphylococcus aureus
.it causes an inflammation in the hair follicles.
In certain cases of wide spread infection a systemic anti biotic is required to eradicate infection.
I would advise you not to touch or squeeze them.Minimize friction by wearing loose fitted clothes.
Take bath with an anti bacterial soap like Triclosan.Start the Doxycycline and complete the course.
You can use an anti bacterial cream like Mupirocin
, Fusidic acid
on the infected areas twice daily.
Hope this is helpful.
