I read your description with interest. Is there any particular reason you say with conviction these are not 'ingrown hairs' because from your description, history & site, they appear very likely to be so. Alternatively, one cannot rule out molluscum contagiosum
which is a viral infection. The treatment of both will be to surgically remove them using a fine 27G needle & forceps or using a hyfrecator
or lasers depending on your dermatologist's expertise or availability of equipment. However, this is speculative. For a more definitive diagnosis, you will have to visit a dermatologist nearest you or contact one of us on this portal using the 'ask-aspecialist' premier package wherin you can upload a clear photograph of the lesion & we can proceed further.
Do hgope this helps you & wish you & your wife Good Health!
