I have sheduled a doctor's appointment this Monday. I'll keep you updated.
I am 20 years by the way, and suffer from minor health issues such as allergies for which I have to take daily medication so I can breathe properly, and skin depigmentations I've had all my life which remind me of vitiligo, which is supposed to be an auto-immune condition. I've heard a bad functioning immune system is a predispositioning factor for tumor development, so I'm a bit concerned. Father told me today that it seems like I'm losing a lot of weight lately, even though my weight is stable. I have been eating a lot more, though, without gaining any weight.
CALL YOUR DOCTOR!!!!!!!!!! My stepdad had a lump under his jaw line- it grew pretty fast and he was also real tierd. His was getting larger though, is yours? Anyways he had lymphoma cancer and had to get Chemo and radiation. You can never be too cautious.
