They could be blocked pores from heat. They may also be mollusca warts--these are not HPV like regular genital warts, and are often not sexually transmitted. of course, I don't know that that's what they are, but you ought to let a doctor have a look, so you can find out and have them treated if needed.

I have looked at pics on the internet and they do not really look like the warts. They are not white in the middle. What would the bumps of clogged pours look like? I did however get a ref. to a specialist. Thanks
