Hi Michaelii! I wouldnt necessarily panic over your latest "bump". I suggest going to your family doctor and get it checked out. It sounds to me like it may be infected if its oozing pus. It could be any number of things besides being something serious. You could need to see a dermatologist, use antibiotic ointment or even just a moisturizer. When in doubt, check it out is a good way to think of these things.

After an area is radiated, heeling is then compromised. Think of it like a dart board. The center is the spot that needs radiation but all around that spot you still get some rads. Its called scatter radiation. This area is much bigger than where the rads was originally aimed. Any sore near this area will take a long time to heel, even if its not in the direct line of radiation.

Good luck with this and please stop back to tell us what it is.
