For the last few days I've had a load of ulcers on my tongue. They're all over, both sides and front and back, and I'm still getting new ones by the day. I'm actually starting to struggle to eat and talk as I'm so sore.
No recent dental work or problems, no changes of health or diet, apart from trying to eat a bit better due to constant indigestion. No other health issues.
Any ideas what it could be due to? I've got a GPs appointment in a week for the indigestion.
