I was playing with my wireless keyboard, then i set it down. Then i felt a water like substance on my palm, then it started to burn. I then touched it with my pinkie and then it started to burn. Where the water like substance was on my hand, it turned the skin white, i then put baking soda and water on the spots and the burning sensation stopped. I then checked my wireless keyboard and found that one of the batteries were slightly oily. Now the problem is that the white spots are still there and arent going away. Should i be worried?
