I'm 20-year-old female, height: 1.51 m, weight 44 kg. I have rhinitis and allergic skin. I have a problem with my jaw. my left jaw looks wider than the right one, such as swelling in the left jaw because of the mass. There is no pain when I touch them, they are a bit hard. doctor said that they're maybe lipoma and have to confirm with FNA biopsy to make sure. actually, I'm not sure they're lipoma because they can't be felt to move slightly under skin when I press on them. is it true lipoma or other diseases? is it okay if I don't go for surgery?
