The electrical zaps came back for a period of one hour on 3/20/18. I immediately took 2 prednizones and the zaps disappeared within the hour and have not returned. I do believe that the prednizone stops the electrical zaps to my head based on the results from these 2 occasions (when in the past I could not find any relief for weeks). As mentioned in my earlier posts, methylprednizone had earlier been prescribed to address sciatic nerve pain and to address nerve damage from a slipped disk in my neck … plus post-hepatic nerve damage from shingles. All three of these occurrences (which occurred in a time span of 5+ years) dealt with nerve inflammation and the prednizone successsfully eliminated the pain. I realize that each of our cases are very individualized but i hope that this information might help at least one person find relief.
