The pain and numbness
in your forehead and temple area is a sequelae of herpes zoster
and is known as post herpetic neuralgia
. The same to some extent can be controlled with drugs like gabapentin
, pregablin, amytriptalline and non steroidal antiinflammatory analgesics like brufen
etc. Herpes zoster does not heal with scars, however if a superceding bacterial infection develops or if the disease was too severe then scarring is a posibility. Now if your scalp lesions healed with scarring then its a possibility that the hair follicles in those areas are completely destroyed. if thats the case. hair growth is unlikely.
Hope that answered your query.
