Good day doc, last night before i went to sleep, i noticed a small lump just under my jaw near my left ear. It hurts when its being touched. I don t know how long its been there i just noticed it last night. I m so freaking out last night that i constantly checked it out. And it moves easily. This morning when i woke up, i forgot it completely until i took my breakfast where i did some thoughts. Just then i remembered it. My left neck hurts for now, but i have observed that everytime i think of it harder, it hurts harder too. What could it be? Please and thanks
