Dear friend.
Thanks for sharing your concern.
As per history posted here, it appears that the discomfort while moving the jaw could be due to two reasons.
Either, it is due to sub mucous
fibrosis or could be due to mild to moderate
fracture in the jaw.
It could also be related to
TMJ (temporo mandibular joint) problems.
Therefore, i would suggest you to visit your oral surgeon and get a
x ray done.
This will help you to locate the exact site of pathology, related to jaw.
x ray is helpful in case of bony pathology where as clinical evaluation will be helpful to evaluate clinically about fibrosis.
Also, please mention if you have any habits like
tobacco chewing or smoking?
For further query please let us know.
Thanks.
Take care.
