Here you have symptoms of numbness on your face ,eye and ears along with the neck. But this is only one part of face that is right half of face. As per the symptoms looks like either you have got issue close to your ear with facial nerve which supplies the face muscles or you have issue with your neck cervical spine and nerves coming out from this level. I suggest to visit a orthopedic because with out doing physical examination and some tests its not possible to evaluate it. Here orthopedic will check the symptoms and will evaluate it. If there is no issue with facial nerve then you may need to go ahead with cervical MRI scan and based in report he will suggest for the medication and physiotherapy treatment for mild to moderate issues. But if there is major damage to cervical spine which I feel there won t be, then he may suggest for surgical correction and then physiotherapy rehabilitation. How ever if there is problem with facial nerve also you need to visit a physio for facial muscle exercises and take advice on precautions like do not have any thing cold food item like ice cream, cold drink etc. As well keep ear bud when ever you go out because the cold air should not go to your ear. And do not sleep under AC or full speed fan. Apart from this you can also use hot water bag for the place from where the pain starts. This will also give you good relief. I have given here general guideline but I am sure it will be useful if you follow it well. Take care.
