are these bumps underneath your skin? like a pimple/whitehead bump? or is it a bump like they are bubbles/blisters above the skin?
if they are bubbles/blisters above the skin, it could be something that i had. they are flesh color and does not affect the complexion/tone of your skin. but from up close, you can see they affect the TEXTURE of our skin. there is no liquid or puss in them as well. when you pick them, a layer of skin can just be removed. the bump will then be gone, but will come back a day later - regrowing itself. and sometimes it would be a little itchy.
if you have that, it sounds like that i had. i had a fungal infection. >.< GROSS. no idea where i picked it up...i prolly touched something dirty. ew. i used the Canesten Antifungal vaginal cream believe it or not. haha it took a while to go away, but i used it for 3 weeks or so..and it disappeared!
not sure if that helped, but i hope your bumps are gone already!
