Patient: When i run or workout that involve my hands moving my armpits develop this foam and i dont know where it comes from. ive tried not using deoderant for that day then work out but its still there.
Doctor: This definitely can be caused from excessive movement of your arms. When you use your arms in a running motion, the swea t created could turn foamy as the sweat contains minerals, lactate and urea. I would try and go see a Dermatologist who maybe able to help you out with some medicated deodrants. Good luck with your running and workouts.
