It hurts so bad I can't do anything without it hurting I struggle with dental health but what even is this
Ok so this lump in my mouth was round at first then this happened it's been causing me a lot of pain when I eat talk or move my jaw a certain way I vape but not often I rarely drink I have bad habits with brushing my teeth, I just want to know how to fix this
Now when I mean safe I just mean will I die because I want to draw my own blood but idk how to do it safely and where to get the stuff my veins are pretty visible so idk if that would help but please tell me how I can do it somewhat safely
