The other thing I would do right away, such as tonight, is some soaks, either plain soap and water, or something like betadyne (which is synthetic iodine), or white vinegar. You might have an antibiotic resistant bacteria, and those things (even soap) can help reduce the infection.
Sounds like an infection or else a really spectacular bruise. You should see another doctor.
