Please Help! IDK what this is. Painful!

In April 2018, I got hit on my chin by my friends elbow by mistake. Doc said i had microfractures in teeth. We did X-Ray, Mri, OPG scans. No current fractures are detected. my impacted wisdom tooth of right side were recently removed in February 2021.  Nowadays, there is popping in my back head, jaw (maybe ear popping) and my upper and lower teeth don't touch completely. Plus, today somehow my right side front teeth (upper) teeth somehow touched my lower teeth while chewing food (particularly rice.) But, yeah it pains. My back head, Temporal Bone near ear and jaw pains sometimes. Plus, i feel pain in my back head. And pull in Above my eyes bones. Forehead sides. IDK what to do. Is it TMJ or TMD. or Did my jaw have any microfractures or did i have chin or jaw or head injury because of that. I don't know. Neither does Doc knows. Visiting Doc said No i can't have TMJ at this age. IDk what this is. Please Guide and Help me! 😭🙏  I have attached two photos of my right and left side teeth.
