You went to the ER for a red/white bump under your tongue? Hard to say but it could be a frictional keratosis underneath your tongue. That's when your tongue rubs against the top of your teeth and can cause it to get a rough patch or area, like a callus. But if its red/white in color, I would still advise you go to an oral surgeon and get a biopsy. They can look under it with a microscope and tell you whats going on.
i felt like crap and still do i didnt go to the er are for them i went for a sore throat and chest pain and i have them and i have three red bumps under it
The red bumps may or may not be related to your chest pain and sore throat. I would monitor the red bumps and see if they stay or go after your chest pain and sore throat heal. If they're still there, then i would recommend a biopsy of the area.
