I used to get swollen tonsils when I was young. Always got penicillin, and all went away. Tonsils are actually good to have.. I would not rush to get removed. Still have mine, and rarely have any issues in adult age.DS has swollen tonsils. Riding through the night with motrin and getting to the doc at 9am tomorrow. He's 5. I was about that age when my tonsils were removed. DW had hers removed as a kid too. I just made changes to our health insurance last month, and now I might be wishing I kept it at the higher premium. Still PPO coverage, but now on an alternative plan that's a lower premium but deductible has to be met before coverage is provided. We expected to hit the deductible, but not until April. Hoping surgery isn't in his future and it's just a script for antibiotics and he gets all better soon.
Hoping for your son to overcome this quickly.
