From the information that you have given it seems that you are having "Pseudofolliculitis".
Pseudofolliculitis results from body hairs that become ingrown generally due to shaving, waxing, or plucking. It is particularly a problem among individuals with very curly or coarse hair. The ingrown hairs result in inflamed bumps and/or pustules. Any areas of the skin that are shaved can develop pseudofolliculitis such as the face, neck, legs, or scalp
I would recommend that:
1.you let the hair grow.
2.I would usually suggest T bact cream for my patients.
3.Use antibacterial soap like dettol
for taking bath
4.If it is very severe then a course of antibiotic with NSAIDS will be needed.
In case of Pseudo folliculitis
prevention is better than care.
1.Avoid shaving with only water or a soap bar. This can cause a more drying and irritating effect.
2.Use a non-irritating, highly lubricating shaving product such as Aveeno Therapeutic Shave Gel, to soften and moisturize the hairs.
3.Shave with, not against, the direction of hair growth. The key is to shave in a manner that does not give a close shave.
4.Use electric razor than manual razor for shaving.
Hope it helps,
