Don't ever worry about being a hypochondriac. It's good that you notice changes so that you can ask your doctor about them. It may just turn out to be nothing or part of the healing process but it's better to be sure. My son had a sore on the side of his tongue and kept putting off going to the dentist about it so that when he finally did, it became a stage two SCC. Your health is very important and the doctor gets paid to answer questions. Let us know what happens.
