Thank you for that additional information and pictures.
Good news. Those spots do not look like any sort of STD or herpes etc.
While it difficult to tell for sure from just looking at a few pictures, those look like areas of minor staph infections from the bacteria getting under your skin near hair follicules.
I do not think those are spider or bug bites, but it is possible...
So. what is the take home message?
I'd wash the areas with warm water and a mild soap at least twice a day. Then apply some triple antibiotic or neosporin ointment (available everywhere).
If things are not better in a 4 or 5 days, or they get worse then have an MD take a look at you in person.
Does this make sense to you?
