I can't help I'm afraid but I have had exactly the same problem recently and would love to know why it's just started.
For the past month or so I have been getting shocks off my car, door handles and almost anything I touch but more recently it's been people as well.
Today I got shocks off everyone I touched, everytime I touched them, kids, adults and the dog. At one point there was a little blue spark from my head!
I'm scared to touch anything at the minute!
