Hello
These could be blocked hair follicles, or blocked oil glands. Sometimes they are known as sebaceous cysts. Since they are lumps and not sores, I wouldn't think they would be herpes. You do need to see your doctor however, because they may be a staph infection of some sort which would possibly be the reason they seem to be spreading.
Try some moist heat, a warm bath, and wash with an antibacterial soap. If they start to drain, a dab of antibiotic ointment. These things might help sooth the areas until you can be seen.
