I was doing a push-up on the floor when I felt a sharp pain in my hand. I thought I d touched a sharp object on the rug. I could find nothing so continued but the pain kept happening as I pressed against the floor. Now I have numbness in my palm just below the thumb at the pad of my palm. I have had the numbness for about a week now. No signs of improvement. I was gardening yesterday and felt the sudden pain when my hand was spread open.
