Pinkie finger and ring finger is tingling i had a little cyst like above that bone on my wrist now it is not as prominent. could that be it

The : The ulnar nerve which supplies the pinkie and ring finger travels into the hand through a channel called guyon's canal. This is separate from the carpal tunnel. A ganglion cyst that develops near guyon's canal can compress the nerve at the level of the wrist and cause tingling. These cysts form on tendons and are pretty common at the wrist. Sometimes they are removed surgically. Other times they spontaneously pop. It is more common for the ulnar nerve to be compressed at the elbow (funny bone).
