Hair Follicle Infection

Hi HV,

My friend had a big follicle infection on his back, just under his waist, that just popped yesterday. He was given 2 different types of antibiotic and 1 anti-inflamatory drug to take. He said he had this problem 3 years ago at the same place. His doctor says that he may need.  Here are my questions:

1. What actually caused such an infection?

2. What kind of treatment can be used (inside and outside) if we do not use antibiotics. I saw that you said the ozone works well for staph infection. Will it work for the hair follicle infection?

3. Could he be able to do something to prevent this from happening?

4. Is surgery necessary?

Your input is very much appreciated,

LongNhi
