I have been facing this problem since a week. Getting tingling needles in my hands and feet while I press them against something and when I lift them in air. I didn't have this problem before. Sometimes I get strange sensation in other parts of hands and feet. I have stated going gym and spend 1 hour everyday with cardio and weight lifting. I was in ketogenic diet when this started so I came back to normal diet but still problem is persisting. I tested electrolytes and sugar (3 times for 2 days) but all normal.
