(Concern) My chest feels tingling, tingling...

It's a bit, it happens quite often...

There are times when my left chest feels so tingling that I need to massage it.

I don't remember exactly, but I don't think it's the right side.

I feel a tingling, prickling sensation only in one part of my left side.

Sometimes I press firmly with my hand.

Because I dislike that tingling sensation,

I have been getting breast ultrasounds every year... there were no abnormalities.

They say cancer can sometimes be discovered after a health check-up... I wonder if that's the case, and I'm a bit scared.

Some people say that it can happen during their menstrual period...

Is this okay?
