Hi, thank you very much for your advice. I'll try 400mg ibuprofen and see the outcome.
I had chicken pox more than 8 years ago; and I'm pretty sure that I don't have shingles.
Other than the above mentioned issue, I don't have any other healthcare problem. Basically I weigh 88 Kg (194 lb) and my height is 6'3 ft, I eat and sleep well, I drink more than 12 liters of water a day, I'm physically active with exercises daily, etc.
Anyways thank you for the comment and the advice; I really appreciate it.
It could certainly be a dental problem. I would start there. You could take an NSAID to ease the pain from inflammation. If you had chicken pox in the past, it could be shingles. If it is shingles, then blisters would erupt in lines that follow the nerve. If that happens you will need to see a doctor right away. Shingles near the eye is serious and needs quick treatment. It could be other causes of trigeminal nerve irritation also.
