Molluscum Contagiosum? In my research this seems like the most likely cause.
We like to scratch each-others backs, and this condition appeared after we did that. The only question is how the virus came into our environment. We are monogamous.
Its odd 30% hydrogen peroxide is not mentioned as a treatment as it is much more precise and less damaging to surrounding skin compared to scraping or burning. Is there a reason the medical community totally ignores H2O2 for treating skin conditions? Wart medication (salicylic acid) seems impractical due to the large area.
How do prescriptions of creams with either tretinoin (derived from vitamin A) or imiquimod work on this condition?
Treatments Your Provider May Prescribe
Removal with freezing (cryosurgery), scraping (curettage), burning (electrocautery), or a laser
Application of chemicals (a strong acid or alkali) or Cantharone (an extract from a blister beetle)
Prescription of a cream with either tretinoin (derived from vitamin A) or imiquimod (a prescription product also used to treat warts, another type of viral infection)
The last photo single lesion does look like molluscum, but the earlier ones do not show the umbilication. And then in most cases of molluscum contagiosum there is no itching associated.
Also in such cases with both itching would look for transmissible cause like bedbugs.The other rashes do look acneform. If only one was involved Dermatitis herpetiformis (Gluten) could be in the agenda too.Do consult your derm.
If the bumps are itchy and both of you are having the bumps, then scabies is an important possibility. Scabies is an infestation of the skin with the Sarcoptes scabiei mite. It is characterized by intense itching, usually at night and by small insect-type bites lesions on the skin. Diagnosis of scabies is made by scraping the skin and viewing the material under a microscope to see the characteristic mite or eggs.
