Im getting slightly worried. The whole day my ring and middle finger has felt a bit number than usual and its similiar to that feeling when it feels like needles are sticking you, but like at alot lower level. Its at the fingertip joint, and recently after playing a little it went warm, but the warmth settled down a few min after i put my bass down. Anyone knows what this is? Just a unlucky day, or is this something i need to worry about?
