Thank you for this question. The question comes from what the problem may be, and this will likely require a visit to a dermatologist
or other specialist in order to first determine this. If the bumps are from large infections that have occurred under the skin, such as inclusion cysts, then these may need to be drained in order for them to heal fully. If instead they are just the small bumps from ingrown hairs that have recently appeared, such as after shaving, then by removing the hair from growing back into the skin and cleaning this area well it may be able to help with the problem. If, on the other hand, you are referring to scarring that has occurred due to small infections or problems in an area in the past, then the best thing to do for these may be to consider some sort of scar revision or dermabrasion, etc that can help to re-surface the skin in a more favorable way. As you can see, the stage of your problem will significantly affect what you do next and how you prevent this problem from coming back. Please speak with your doctor
about this question.
