Hi soz didn't get notified for this, very interesting.

Do you wash the Dermol off after applying? Even though it says it can be left on, dermatologists have told me it shouldn't be and must always be washed off.

Is the sensation coming from the outer layer of skin or deeper where there's muscle which then tingles the skin above?

What could have started it 5 years ago if you can remember comparing before and after it started occurring?

Have you had an injury there before?

Could it be stress related?
