Small hard bump on penis shaft

Hi so I just noticed this white bump on the lower part and it's slightly painful when I touch it. It feels soft when flaccid. I did some research and apparently it might be a lymphocele, which appear when lymph collects somewhere. I'm 14 and want to know whether this needs actual medical attention or is normal. Thanks

they go away by themselves

Thanks but it’s gotten larger and is hard to touch. It’s also very sore when I walk around. Is this normal too

u should visit a doctor in that case
