Dear patient, Thanks for your concerns. Indeed, these residual symptoms may reflect nerve damage from the zoster (varicella virus reactivation); they may manifest as strange sensory manifestations or recurrent pain. The course is variable, some patients recover normal fucntion while others experience recurrent symptoms in the abscence of the rash. There are some medications like gabapentin and pregabalin that may help settle down the peripheral nerves in case that a neuropathy develops, and I would encourage you to discuss these types of medications with your primary or perhaps even a neurologist specialist. Yours truly, Dr Brenes-Salazar MD Mayo Clinic MN
