Strong nose sensation whenever I feel spiritual love

[Whatwhat]

I do loving kindness meditation regularly.

Whenever I send love to me or others I feel strong sensation on my upper nose.

It feels like someone is pinching my upper nose.

When the meditation gets really strong the sensation also gets strong. Sometimes it's too strong it feels numb. 

It's quite useful to know whether I am doing the meditation right or wrong. But I'm also curious, is this just me?? I've searched online and never found a similar case

Is this some kind of Chakra? I have no information about the field.
