Hi.
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain pain in back of the jaw and difficulty in opening the mouth does not always relate to TMJ and in your case it seems to be related to Wisdom tooth as there can be
PERICORONITIS which is inflammation of the gum flap over the wisdom tooth which can get inflamed due to either infection caused by food deposition between the gum flap and the wisdom tooth or being bitten by the opposite jaw tooth.
The inflammation can lead to
severe pain in the area behind the last tooth as well as pain in back of jaw which can radiate to entire jaw on the affected side..
As the inflammation goes down the pain can subside..
The other cause can be due to infection or clogged duct of submandibular
salivary gland which is present just below the jaw line and pain in jaw can be due to it also..
It seems less possibility that it is due to TMJ in your case but cannot be ignored and you need to consult an Oral Physician and the physician can advise you to get a full mouth
x ray that is an OPG done and in case if salivary gland problem is suspected an MRI or
CT SCAN can help in making the final diagnosis and get treated as per the diagnosis..
As of now you can take
Ibuprofen [
Advil or Motrin] in case if you have pain..
Hope this information helps..
