Generally the more information one has, the better. But if there is a reason you would wish to hide a potential ability from your village, I can understand your hesitance in taking the test.

I see. May I ask how often this happens? If there is some kind of regular schedual, it might be possible to link the feeling to a season or monthly cycle. And if the occurance is becoming more frequent, it would be important to discover the cause as quickly as possible.

The more you speak of this, the more it sounds like an external jutsu, perhaps designed to either keep you away from someone or a group of people, or to overtime corrupt your skills. Especially if it is uncommon to experience it within your village's walls and protections.

Not knowing your position, I cannot guess as to why it is targeted at you, however.

I would be happy to help with interpretation. This is far more interesting than putting on bandaids and healing bruises.
