Upper Molars feel tight and stiff.

Is this normal? I am on day 3 after upper  WT extraction. My upper right WT. Today I feel so tight in first and second molars upper and lower while closing the mouth. Is this normal? Also , I don't see any swelling in the cheeks. But see some swelling in the gums on extraction site. I feel more pain in the ear. Inside the ear. Is it normal ? I get constant pain in the ear and in front of the ear. Why the bite is so hard and stiff on that side? The molars hit so hard and my ear hurts. It's like burning, sore scratching pain in the ear. While closing the mouth, the first molar upper bits the lower first molar first and it's so hard and stiff. What is the reason? I had lower jaw pain and swelling before this extraction. I still have those. Don't know the reason for this yet. Dentist said could be TMJ issue or upper wisdom tooth issue. So removed the upper wisdom tooth. Still have low jaw pain and swelling. Why the molars hit first and hard while closing? It hurts my ear while biting
