Hi: I'll assume your tongue is swollen, accounting for the difficulty when swallowing. If so, you need to determine what caused the swelling. Is there a popcorn kernel stuck in the tissue? Did you abraid the area when clearing out the other kernel?
If you don't feel that there's any swelling and the tongue just feels sore, like an overworked muscle, then you may very well be correct, and muscle strains take time to recover. I'd like to say don't swallow for a week, lol, but the point is the same as treating a sore muscle......rest.
If the area of soreness is far back in the throat area, I wouldn't be too concerned with it being related to your ear. However, due to not knowing just where the soreness is, if the ear pain gets worse over the next few days, you may have an infection and need to see your doctor for some antibiotics.
Regarding the soreness, Advil, the green gel caps work best, XXXXX XXXXX capsules, every 4-6 hours and this will help with the inflammation and if nothing else is implicated, should help with the inflammation.......give it a week.
I hope I've been helpful, and thank you.
