'I've got blisters on me tongue'

Over the weekend I somehow burnt or bit my tongue but I can't remember. I asked my friend whether I may have had a 'seizure' during the night cos i stayed over at hers and she said no, so in a way I went with the burnt tongue option. It may be a cause of stress as well since I work in a rather stressful environment.

I have had one or two blisters on my tongue in the past due to high bloods but now a cluster of these pus like blisters (of around 5-6 of them) on my tongue are very sore and won't go away. Does anyone know how to cure them or just to stop them getting even worse? I also know us diabetics heal slower as well but I just can't take the pain anymore.

Thank you :')

 

I do have white fillings so maybe that might be the cause for it...However, I've got a dentist appointment in 2 weeks time so I can ask then

Thank you for your help x
