Yesterday, I was using washing machine. It is a semi automatic type, i.e it contains two separate drums one for washing and another for spinning (drying). After washing, when I started taking out the clothes, I felt slight pain at the edges of my hand fingers. Earlier also I experienced the same, but I assumed it as pain from nails. I think this tingling pain is because of static charge generated during rotation of the washing drum. This charge may be dissipated if I do not touch the machine for few minutes after stopping it.
