Sharp pain in lower jaw after yawn

Something odd:

So for the past week or so, whenever I have yawned, immediately after an incredibly sharp and intense pain is felt behind my chin. It’s really painful and it lasts for sometimes up to 25 seconds or so. I would like to know what this is. 

It could be Temporomandibular Joint Disorders (TMJ).

I also think it could be TMJ better to get it checked
