Tension in the third eye region after frequent cannabis consumption?

I'm a regular consumer of cannabis and somewhat recently I've started feeling tension in my third eye region. Originally, I assumed the tension in my third eye region was due to practices like meditation but now I'm not so sure.

I've had periods where I don't use any cannabis and the tension in my third eye region appears and remains for days or weeks, then I start using cannabis again and the tension goes away. But I've also had the opposite happen, where beginning regular cannabis usage becomes almost a sure way for tension in my third eye region to return.

When it returns it can last days or weeks, whether or not I consume.

Mostly I've been ignoring it because I'm not sure there's anything to do but does anyone have any feedback on this experience?
