About a month ago I discovered a lump in my neck. It is hard as a rock, doesn't move. It doesn't hurt or itch. It's in the back of my neck (lower part), close to my spine. It's about the size of a bean.
Also, I've been tons of other symtoms, I don't know if they are related to the lump. I've had sore throat for months (no cough), tinnitus for about a month, mild/moderate pain in ears that comes and goes, lighter periods than normal, stomach symptoms (alternating diarrhea and constipation, gas, loud stomach noises), muscle twitching all over my body (mostly in the legs). I'll make an appointment to the doctor tommorow, what diagnosis should I be expecting?
I'm sixteen.
