Jaw pain and face shape changed. Pain?

I used to have round solid shape face before. I am having lower jaw pain for 3 years now. No changes her even after seeing many dentists and surgeons. No reason given. Taken cbct and MRI of tmj. I noticed my face shape has changed to very very narrow and thin . I used to have nice round shaped face before. Now I have very narrow shape near the cheeks and it looks very very narrow. Is face shape changing normal? Will it go back to normal old face? I have constant pain in the lower jaw under ear area and mandible end. Face shape changed immediately after few months of this pain. It stays the same. Tried different medicines and treatments.  Nothing helped so far. I have pain in right side lower jaw.  I am not chewing on this side since 3 years..chewing hurts too. I can't chew on any solid foods. Is there a chance to get back the  face shape normal with jaw pain?
