I can see that you are online, so i am posting my answer.
Shingles is caused by a virus called the Varicella zoster virus.
Shingles develops in 3 stages, these are-
1. Prodromal stage (it occurs before the rash appears)- Symptoms in this stage are- Pain, burning, tickling, tingling, numbness occurs in the affected areas around nerves , this can last for several days or weeks before a rash appears.
2. Active stage- Here a band, strip, or small area of rash appears.Then Blisters will form. At this time, pain is severe in nature. Usually rash will heals in about 2 to 4 weeks.
3. Postherpetic neuralgia (chronic pain stage)- This can be complication of shingles. It occurs primarily in people over the age of 50 and affects 10%-15% of people with shingles.
If treatment is started within 72 hours then it can reduce the severity and duration of the symptoms, also it can reduce the complications.
The line of treatment is- anti-viral drugs along with painkiller and corticosteroids.
Common anti-viral drugs are-
If pain is severe, then doctor advise for-
-Anticonvulsants, such as gabapentin
-Tricyclic antidepressants like amitriptyline
-Also Numbing agents, such as lidocaine, can be very helpful.
I advise that you should not delay and rush him to ER ASAP for prompt treatment.
