I have the most pain under the left side of my tongue that radiates to my left ear and the left side of my neck. I think it might be a swollen gland because I can feel the swelling under my tongue and when I put pressure on my neck, right under my jaw, I can also feel swelling on the inside. There is no visible swelling or bump you can see on the exterior, but I can definitely feel it. The pain in my ear is more achy and annoying, but the pain in my tongue makes it hard to eat and talk. As far as I can tell,l there is no discoloration nor sores in my mouth. It's been like this for about a week and I've had it before, but not for a while. It seemed like I used to get this about once every month and it'd last about a week or 2. I don't know if this is my body's way of fighting off infection or if it's something else? Maybe R/T teeth? It's definitely distracting, painful, and baffling. I am an 18 year old ,average sized female, never been hospitalized or had anything more than a bug. Thanks!
