Ive often noticed my left pinky and half of my ring fall asleep, its never the whole hand. i went to the doctors for pain in my elbow a few months back and she said it was tennis elbow. should i make another appointment?

You symptom is consistent with ulnar nerve entrapment syndrome. If possible, you see an orthopedist or neurologist. The entrapment can be at the elbow or the wrist but likely at the elbow in your case because you had elbow pain several months earlier. You will need elbow imaging test for ruling out structural lesion which requires surgery. Otherwise, you will be treated with physical Tx. Good luck
