I've had this issue or non-issue for as long as i remember and never really paid much attention to them as it never affected my life. I get these single raised, sometimes flush and not raised, red bumps appearing anywhere on my body, I usually notice them on my arms and even unnoticeable. At the moment i could probably count with my fingers
are damaged by friction from clothing or blockage of the follicle.
Please keep the area clean and apply some topical antiseptics. Also wear loose-fitting cotton clothing and use an antibacterial soap or mild soap like dove. Avoid any kind of cosmetics and do not pop the pimples. Topical antibiotics such as mupirocin or neomycin containing ointment are also useful. In case the symptoms persist then oral antibiotics may be needed. Please consult a dermatologist in that case.
