My right hand keeps tingling. then pinky hurts, then palm too. whats going on?

Ulnar nerve entrapmt: It is likely that you have ulnar nerve entrapment--the nerve traveling through the groove of your funny-bone/elbow area. Symptoms often occur during sleep or when having your elbow flexed such as hold a phone to your ear for awhile etc...Typically keeping your elbow straight will resolve your symptoms. You may want to consult doc for an eval and treatment...Good luckl.
