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?
I haven't had the "throat" experience, but it's not uncommon to have long or recurring periods of some kind of weird painful or uncomfortable physical/somatic sensation. Teachers that I know of link it to the "knowledge of the three characteristics" phase of the Theravada "progress of insight". It's a sign of maturing insight into the non-self nature of your physical and mental sensations. 

It's not a reflection on you or the state of your practice- in fact, it may be a sign that your practice is healthy and getting results.

However, if it starts to be accompanied by disturbing imagery or strong negative emotions, especially if it seems linked to memories of past potentially-traumatizing experiences, then reduce your meditation periods and look for professional psychological support before continuing intensive vipassana practice. However, if it stays purely physical/somatic, then it's not that unusual.

You just won't feel equanimous about it in the short term, but your non-equanimous feelings about it can be part of your vipassana practice. Examine the sensations in terms of "vedana" - the quick arising and disappearance of pleasant, neutral, and unpleasant feelings.
