Hi, I am a 26 year old male. Ive got a 1/4 inch white spot on the left side of the roof of my mouth, towards the back of my mouth. It has increased redness around the spot.  Hurts when I drink, swallow, and eat.  Also, Hurts throughout my left ear.  Any suggestions would be greatly appreciated.
Thanks for your query, I have gone through your query. The red and white patch or area could be because of the fungal infection like candidiasis(erythematous candidiasis) or erosive lichen plans. Consult your oral physician and get yourself completely examined to rule out these conditions. If it is candidiasis you have to take topical antifungal agents like candid mouth paint. If it is lichen plans then you have to take topical steroids like triamcinolone acetone 0.1%. I hope my answer will help you. Take care.
