I have eastern painteds as well as a RES. Their care is similar. The bump really sounds like an abcess (but a pic would still be good), and it should be lanced by a vet to allow the pus to drain out, and your turtle may be given antibiotics to treat the infection. If the vet that's 4 blocks from you is a herp vet, call them and ask about fees. If not, I'd still call and ask them if they know of any herp vets in the area. If they don't, check the link at the top of the forum to locate one near you.
Does your turtle have any other symptoms besides the lopsided swimming and sound he's making? (Open-mouth breathing, wheezing, mucus from the nose or mouth)? Will he eat? Lopsided swimming often indicates pneumonia, and your turtle should really be seen by a herp vet to be treated. While you're looking for one, up the water temp (get a submersible heater) to about 82F, and make the basking area 91-92F. If the weather isn't warm where you are, I wouldn't take him outside at this point, especially if it's not that warm and breezy.
Don't delay finding a herp vet---an abcess won't go away by itself, and since it sounds like he has a really bad infection, he most likely will need to receive antibiotics. The sooner he's treated the better his chances of recovery. Good luck. Let us know how he does.
