Feeling pains buhari tells nigerians

I think there may be a slight mistake here. It seems like you meant to say "feeling pains, Buhari tells Nigerians" instead of "feeling pains buhari tells nigerians".

If that's correct, here's a possible completion of the sentence:

"Feeling pains, Buhari tells Nigerians..."

This could be a headline or a news article about President Muhammadu Buhari of Nigeria sharing with the public that he is experiencing physical or emotional pain.
