So one night, i was using the laptop and suddenly my back and neck hurt. I think it's because of my bad posture so i did a bit of stretching and headed towards my bed. As i lay down, it still hurts so i try to touch my left neck to see if a bump is there. Then that's when i felt a lump, it's kinda hard. It's been 4 days since i noticed this. It's not actually getting big but i'm reallly scared if it's cancer or lymphoma ;3; I've been taking antibiotics for 4 days now, and i also have phlegm. Also, the day i noticed the lump, i'm having menstruation at that time. I don't have fever/chills or night sweats. When i lay down on my right side, that's when it's really noticeable. especially when i move my shoulders up. What is this exactly? I'm getting scared right now
