“My husband has been suffering with “Opthalmic Branch Post-Herpetic Neuralgia” for more than 4.5 years. The area describe here is exactly same as his PHN area.
Currently he is taking 600mg Gabapentine 3 times a day and have tried numerous other pain killers or/and antidepressants and nothing helped.
How can we contact with the doctor who can perform the nerve block described here?
He is 62 years old, 165 lb., borderline diabetics, 1 stent from angioplasty, otherwise healthy male.
We would be very grateful if you can send us the information regarding this treatment.
Thank you very much in advance.”
I’ve written about this before here:
Treatment of Opthalmic Branch Post-Herpetic Neuralgia with Blocks
However, it is such a horrible disease, I’ve decided to write further:
Initial test block
A test dose of 3 ml marcaine could be given to inner 2/3rds of eyebrow horizontally under skin – any doctor could do that.
Your doctor could easily follow the pictures above – print it out and take to her/him.
If temporarily effective, a combination of 4% tetracaine dissolved in 0.5% bupivacaine (0.2 – 0.5 ml) into supraorbital or infraorbital foramen – gave relief of trigeminal neuralgia relief for more than 3 months in one study. The latter might require an anesthesiologist or pain specialist.

Description of injection here
Pontocaine can be gotten as a powder in vials to which 0.5 mls marcaine can be added.
Don’t forget freezing eyedrops might be effective as well:
