Those "firestorms" may be activation of Herpes virus in the ganglia of the spinal cord.
If you search "Zoster" or ganglion in our search at the right top of the first page of PN index of posts, you'll find many posts.
You can have blood work for both simplex and zoster to show if there are high viral titres present. If so, some antiviral drug treatment may help.
Ganglioneuritis is the medical term used for this.
Herpes tends to activate in spring, and be more active in summer.
You can also try to put the herpes down with L-lysine orally. 2 to 3 grams a day may help with spells of activation.
