Hi there, I've also been getting the same types of electrical shocks on my scalp in clusters today, plus some pain behind my left eye. I know a lot of folx have mentioned trigeminal neuralgia, but my research turned up several other possibilities including: migraine aura, occipital neuralgia, MS, certain medications/withdrawal from certain medications (especially antidepressants), excessive alcohol/drug use, B12 deficiency, cervical disc issues, gout, trauma to that area of the head, blood vessel inflammation, partial seizures, tumor, shingles, anxiety, and others, so there are a lot of other possibilities. Still a good idea to get addressed by a neurologist and get some imaging of the neck and head/brain if able! Best of luck to everyone!
