Tooth and Mouth Problems

I am having ulcer type patch with redness in my mouth near throat n this is resulting in pain in ear as well. Pls advise.. attached photo for reference..

I have lower jaw pain with swelling, ear pain and tenderness under the ear and on top of the neck for 2 months.  Went to the dentist and took pan xray. Dentist said it's because of my upper wisdom tooth or minor crack in lower first molar. Removed the upper wisdom tooth 10 days back. But still the same pain and swelling. Had an online consultation with another dentist, he said I have Dislocated condyle on left side. Is that true? I don't have any symptoms on the left side. But my symptoms only on the right side. I don't know if it's true. My symptoms started 2 months back. Before it started, I did lots of chewing one day(soft foods only) and immediately after eating, I had tightness in the upper right molars. Next day jaw pain and swelling started. What could be the issue? What should be my next step? Minor crack cause these symptoms?

The dentist told me to get 4 of my premolars extracted for straightening my teeth. I really don't want to extract and retract and I have seen so many negative facial profile issues post treatment of extraction therapy. I came across non-surgical palete expansion and Is it possible to make some space with that procedure? Or is there any other alternative besides extraction-retraction? Where can I find a doctor in Chennai who does that? I'm 20 years old and I don't want to reduce my tongue space and contrict dental arch.

Also I have taken 3 doses of Keterol DT but still the pain is very very very severe. Even if I touch my tongue near the pain area it pains. Please help. The pain is very very severe. Our home area is under lockdown. Kindly suggest so that for temporary the pain can be eradicated. Thanks
