Thanks for writing in.
I think you're suffering from a pilomotor seizure
. these seizures usually come from the temporal lobe
in the brain. This is a condition where due to a problem in the brain, the person gets recurrent attacks of goose bumps.
at this stage, you need to see a physician and get a CT scan
or a MRI
of the brain done. There are several other causes of such symptoms but since you dont have any other symptoms, our first step should be to rule out a problem in the brain.
Hope this helps.
