Hello my friend @Abooz_2001M, it's nice to see new members in the Fitbit forums. Since you mentioned that your tracker is a Surge, I've moved your post from Charge HR to Surge board to keep the forums organized. The green lights flashing in the back of your Fitbit are the PurePulse LED lights, this is used to illuminate the quantity of blood passing by your wrist, this quantity is reflected and captured in the panel located between the lights and this gives you the bpm in your Fitbit. The PurePulse LED lights are on the visible spectrum, similar to the lights in your home or office, this means that the lights have very low power so they won't burn your skin.

The pain you are experiencing is a compression of the ulnar nerve.  This nerve supplies the little finger and the hand. When there is prolonged compression, as with the Fitbit pushing on the area when you lie on your hand at night, the ulnar nerve becomes irritated, causes pain, may cause numbness and tingling too.

My suggestion now is following the tips posted on the Wear and Care page, however since this is a more serious problem I've escalated this situation to our support team, please check the inbox of the email address you used to create the Community account, they'll contact you to give you more information to help you out.

I'll be around.
