Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain the symptoms of pain in ear, jaw, cheek, and forehead can be due to causes like tooth infection
, disorder associated with jaw joint also known as Temporomandibular joint disorder, while can also be due to nerve induced pain known as Trigeminal Neuralgia
Pain in cheek and forehead can also be due to sinusitis
A proper diagnosis can be done only after a thorough clinical evaluation..
I would suggest you to consult an Oral Physician and get evaluated and he can advise you to get a full mouth x ray done known as OPG to rule out for teeth and jaw joint problems..
In case if there is no dental problem ruled out you should consult an Otolaryngologist and he can advise you MRI or PNS view of sinuses, CT Scan and nerve conduction studies too rule out the exact cause of problem and treat you accordingly..
As of now you can take Tramadol
to relieve pain..
Hope this information helps..
Thanks and regards.
