Make sure you do not wear those bands again. Keep your arm elevated over your head for a few minutes Wiggle your fingers and wrist. If no improvement or it worsens, see a doc.
Just stop wearing the bands and talk to your doctor about it.
should do, think its just trapped blood which will go down
If you would like to give a thumbs up to my answer with your own thumb take off those bands before a lack of blood flow kills the nerves in the arm.
