Hi dear , The symptoms you mention in query are pointing towards a condition known as Oral Submucous Fibrosis (OSF) . Oral submucous fibrosis (OSMF) is a chronic precancerous disease that results in progressive juxtaepithelial fibrosis of the oral soft tissues and TMJ is one of the prominent symptom in this condition . I would suggest you to consult oral surgeon for proper diagnosis . Doctor will take history and do clinical examination . Doctor will also look for trismus, stiff and small tongue, blanched and leathery floor of the mouth, fibrotic and depigmented gingiva . doctor will give local injection of placental extract and Methylcobalmin injection . Jaw dilators exercises will be helpful . Doctor may also prescribe lycopene . Do warm saline rinses , start physical therapy of jaw , speak less and eat soft . Give proper rest to your jaw . Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
