HelloI was referred to a specialist to remove a wisdom tooth but after the procedure I'm having tmj pain due to my mouth being open too wide/long

During the procedure I kept feeling pains so he had to inject me with more and more local anesthesia and he kept pushing down and widening my mouth to get the tooth out. About a week after the procedure after experiencing clicking/popping and pain in my jaw( near my ear), I called and went back to the dentist who then told me I may have something called tmj due to my mouth being open too wide/long during the removal. He recommended that I finish my meds, continue with a soft/liquid diet and warm towel applications. I also found out that he actually is a student dentist and had to consult with the dentist... So far I'm not improving, the pain seems to be getting worse.I can barely open my mouth wide enough to fit a spoon while I'm eating, I can't pull out my tongue ( so brushing my tongue and back teeth is very painful), eating in public is embarrassing, kissing my bf is not possible at the moment. I read up on tmj online and no cure I'm very scared for the future. I hope you can help.
