For the last 2 weeks my tongue and bottom lip have felt raw and tender. It started with a couple canker sores on my bottom lip which I thought was due to stress or food irritation. This happens fairly often to me. But, now I have a layer of white stuff under my tongue and on bottom lip. The stuff on my tongue almost looks fuzzy and can’t be scrapped off. I have pretty bad anxiety and this isn’t helping. Is this something to be worried about? Do you know what it may be? And ideas would be appreciated. Thanks
