Pain in Wrist

I have an Apple Watch and have had it for several years and wear it daily (not while sleeping) with no issues. However; a couple of weeks ago I started feeling what feels like a bruise on my wrist. I took the watch off for a couple of days and it resolved. I put the watch back on and boom, the pain returned. So, I moved the watch to my other wrist and after 2-days of wearing it on that had (which had no issues before I moved the watch to that hand) I started feeling the exact same pain in the exact same place. The pain is still there in the other hand though, even a few days later. It is on the back side of the hand, right where the watch itself sits - not the band. I do not wear it too tight either. Has anyone gotten anywhere with this issue? I'm a little worried!
