Thanks for posting your query.
The clicking in ear can be due to dislocation of Temporomandibular joint.
The dislocation can be felt using palpation with fingers on the affected area.
I would suggest you to avoid wide mouth opening.
Any fracture/infection can be ruled out through x-ray of the affected area.
pLEASE do visit an oral surgeon and get jaw fixation treatments depending on the severity of the condition.
COmplete course of antibiotics has to be administered.
also cosult with an ENT specialist
to check any ear infection
