My thumb hurts to move like a 5-10 most of the time some motions are a 7-10 and its a little stiff it hurts to even hold a glass of water and the pain is on the outside of the thumb where the finger connects to the hand its not entirely on the joint its right above it twoards the tip of my thumb. I feel like it could be a hairline fracture it hurts but i can still move it much like if you broke a toe
