Apple Watch battery causing wrist pain

I have been wearing my Apple Watch for over a year now. I started getting fatigue and pain shooting into my wrist on the site where the battery touches my wrist. My band is not to tight. I switched arms to see if it happened on the other wrist and within 30 minutes it started with the same pain coming from the battery. Can the batter get old? What is the solution to this?
