How concerned should I be over small white bumps under the skin that surface when the skin is tensioned?

Thank you for the question. It does seem that these lumps arise from deeper in the skin. The doctor will have to examine and palpate/feel the bumps for a proper assessment. In some cases, a skin biopsy may be needed to confirm the diagnosis. I do think that you should bring your son to see the doctor or dermatologist to be examined to advise you on the proper diagnosis.

Hi, The white bumps are likely milia (“oil” seeds) forming just beneath the skin. This may have occurred due to surface injury caused by the tattooing process. A close physical examination by your doctor is needed to confirm the diagnosis. After confirming the diagnosis, the milia may be removed by making a small nick on the skin and extracting the milia seed under topical anaesthesia. Hope this helps!
