After asking around, I found out they were swollen
lymph nodes. They have been swollen
since. And since then, I've had swollen glands
around my collarbone, in and around my armpits, and around my groin. Its on both sides of my body, and some of the nodes are quite large. Anytime I notice a new one, its because its quite tender to the touch, and sometimes even general movement (especially in the armpit).
