I'm having a similar problem, the 3 days again I felt a stick on my upper right arm when I looked I saw 5 tiny white bumps in a hill like cluster, they itch now but this is after I applied Whitfield ointment and read some itchy stuff online, not sure if it's mind over matter is this serious though?
Hello,
The symptoms are suggestive of folliculitis and there is nothing to worry about but the other possibilities are of viral rash, heat rash, sweat dermatitis, boils or cysts.
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. 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.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
