Inflammation of the oral cavity

[MarioBruno]

Hello everyone, since 4 weeks I have on the inside part of the cheeks an inflamamtion and it s looking red inflated since it gives me problems to eat normally. I have been through Curasept with clorohexidine mouthwash for almost 3 weeks, which I took originally for inflammed gums that are now gone (plus when I use it it gives me a sensation of burning and I think it is bad). I have also been through oral hygene and I modified my diet which now consist in lots of vitamins, iron, zinc and everything at ambient temperature but the inside cheeks are still red. I have also been through antibiotics for 6 days for another reason. What should I take?
