Possibly an ingrown hair? I get those from time to time.
It could be a boil my brother used to get them a lot
that's odd cause i noticed that also few days ago & hmm.
It could be your lymph nodes too. It will look Like a pimple or something and be really sore.
it doesn't hurt or it's not pink/red. doesn't bother me but the lump is just there. so idk
Does it go away on it's own or do I need to do anything?
What do I do if it is that?
If it's your lymph node it just means your body is fighting off something. Nothing serious just your immune system doing what it's suppose to. It normally goes down after a couple of days.
If its where you shave heres my question. Do you use the sane razor that you leave in the shower or bath tub area for a couple uses before changing?
I had a boil under my armpit once. I knew it wasn't a tumor because within a day the size almost doubled. I had to go to the doctors to have it lanced. If it's under your left arm get in sooner than later because if it's an infection it can be dangerous for your heart.
Yes but I just changed the blades
