Strong tingling sensation in face that persists +- hour after meditation I've been meditating for about 8 years.
Recently I did a second vipassana 10 day silent retreat. 

A few days in, when focussing on my face, my face got highly sensitive, and a strong tingling was felt in it. This feeling intensified when focusing more on the areas where I would place my attention. Even focusing on parts of the neck and throat would have the same effect on the face. 

The sensations would last after meditation and subside after about an hour or so. My teacher assured me that it happens more often, and I should probably not focus too much on my face. 

I'm slightly worried about it still, and decided to fully avoid the face area for now, and take it easy meditating altogether. 

I was wondering if others had similar experiences, alternative interpretations, and other ways to work with it. 

Thank you!
As you progress in meditation you will start feeling sensations in different parts of your body. At some point, you will feel sensations thought out the body.

There is nothing to get alarmed. Also, do not get attached to it. Simply continue your meditation.

Do not avoid any areas and also do not stay long in any area than others.
