Got back from the doc

He isn't sure what it is. He put me on an antibiotic withthe hopes that I just have some sort of infection causing the swelling. He also measured the lump and we will keep track of it. I have an appointment next Wednesday, and if the lump hasn't started decreasing by then he will probably have them do a biopsy on it and completely remove it. He is concerned about lymphoma or leukemia being the other cause of the lump.
