Could small white bumps behind the penis foreskin as well as sore small patches of redness be a STD?

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!

Multiple small lumps beneath the skin can be due to the presence of multiple cysts in the skin and some individuals may be more predisposed to developing multiple cysts in the skin. As these lumps are better felt than seen during a closer examination, it would be good to see your doctor or dermatologist so that the lesions can be more properly assessed given the proper diagnosis for the condition. Sometimes, a skin biopsy of the skin bumps may be needed to confirm the diagnosis. With the proper diagnosis, your doctor can then discuss the necessity for further treatment with you.
