I have a burning pain in between my left pointer and middle finger. it's usually when i get home from work i work as an esthetician?

Overuse: If you're using your hands and fingers a lot during the day, it's similar to what happens to people who type a lot... The fingers get sore, they get tired, and they need a rest. The fact that it's happening after work is more evidence that you probably need to take more frequent breaks to give your fingers a rest. Or modify your technique to minimize repetitive motions.
