Severe sensations in throat during Vipassana

I have had very strong sensations in my throat since I started practicing *Vipassana* 2 years back. They keep changing shapes and sharpness - they started like a picket fence and now are like hard pokey stone(s). They get overwhelming at times and am not able to focus on other body parts. - Has anyone experienced something like this ? - Have you managed to be equanimous in the face of sensations that seem to be ***communicating*** with you?
