A few months ago I found a tiny ball under my skin right under my knee, it feels like a tiny bb pellet, it moves around but it doesn't hurt. I asked my mom to feel it and she said it was just calcium deposits and that I should drink more water to flush it out. So I did and it never went away but I thought it would be fine according to my mom so I ignored it.
But now today I found another one on the right side of my lower back. This one is a little bit bigger and also moves around too. I'm starting to get worried that it's cancer and I wonder if I should ask my doctor or if it will be okay.
