What are these red itchy little bumps on the bottom of my feet?

Dermatitis. There are many causes, including fungal (athletes foot) infection, bacterial infection, contact dermatitis or allergic reaction. If it is more than a small area, spreading or getting worse then you need to see a dermatologist or podiatrist asap.
It could be... Athlete's foot. The best otc medication (in my opinion) is lotrimin (clotrimazole) ultra. Dilute vinegar soaks are good as well. Dry the inside of your shoes by placing them up-side down over an air return vent at home overnight. If this doesn't make things better in a couple days, see a podiatrist.

Small red slightly raised circular bumps on my feet. It's not itchy and I assume some sort of bug bite. I was in a swampy area and this skin exposed.

No treatment. If the rash is asymptomatic except that it is there, you really don't need to treat it. Thee are many things that come to mind after wading around in a swampy area - something obviously irritated the skin. However, if it's not bothering you (no itch, burn, etc), no need to put anything on it. Just monitor and see what happens over the next week. If other question, please let us know.... Read more...
