I'm sure it's nothing as extreme as MRSA; see what they say tomorrow
Either way, you're doing the right thing in going to see someone ASAP about these lumps. Sometimes it really is impossible to diagnose something like this with descriptions over the internet; the best thing is to not try and diagnose yourself in order to save yourself the worry (or downright panic) of having something very nasty when it's often just something pretty benign, save that for the Doctor to sort out.
