i sometimes pop the bumps and a oil type substance slightly comes out. I have popped a few and left the many others alone.
I'm sorry that I can't tell you exactly what this is. When you say "they stay scabbed over," that makes me wonder whether you ever pick or scratch these bumps, because that's pretty much the only way scabs form. I suggest you absolutely avoid any picking or scratching and show your problem to the dermatologist, or perhaps a different one. Folliculitis does sound possible, by the way, because there are tiny follicles all over the body, and the condition does tend to come back, off and on, for long periods. But leaving the spots alone is essential for proper diagnosis.
Best.

also i have visited the same dermatologist 8 times and he can't figure it out.
