There is something movable on my neck do not know if its a lump, cyst or lipoma but let me tell you it is very hard to grab it and it’s freely movable very easily. It’s been there since I don’t know for how long but I noticed it 2 months ago, I don’t think it changed in size. I have no other symptom no night s. or itching but fatigue due to the lack of sleep. I’m 17 years old. I’m not really worried but I wanna know what do u THINK it is?
