Hi @susanbo2457, welcome to Mayo Clinic Connect. First of all, THANK YOU. Thank you for working in a supermarket during this lockdown and risking your life. I'm sorry that you contracted COVID-19, but am grateful that you are here to tell us about it.

While you've recovered, you mention that you're left with a persistently irritated tongue and a sore on your gum.
I'm tagging other members who have had COVID-19 or a suspected case or a family member who had COVID, like @sueinmn @mkqq @ccbelle @wishercristy @potterylady and @amart22018. They may have had a similar persistent symptom.

Susan, is the sore on your gum like a canker? What have you tried to relieve the irritations in your mouth?

It's possible that it's a canker but I don't think so more like a bump that is sore. I find a canker to be more irritating.
I had implants put in about 5 months ago on the other side of my mouth and am using the mouth wash the surgeon gave me to use, It's called Paroex and it seems to help but slowly.

@susanbo2457, I once had a similar bump on the outer part of my gum a year or so after I had a root canal on one of my upper teeth. It turned out to be a small piece of bone that had broken off and was "floating" under the gum. It finally worked it's way close to the surface and broke the skin and I wiggled it out myself. In retrospect I should have went to a doctor/dentist to have them remove it. If the bump feels hard I would have a dentist take a look to see what it may be.

I forgot to mention on the night I had the high fever 103.5 the hearing in 1 ear is diminished. that hasn't come back yet and I'm wondering about anyone else having that happen.
yesterday on your symptom page I saw confusion as a symptom and I had that. that's the night I went to the hospital as my dr. was afraid of a stroke. That was all I could explain is that I was very confused.

I thought of that but it's too soft. thanks
