Hi,
I am sorry to hear about for long-term pain. I will try to answer your question as simple as possible with the best of my knowledge. The pain after singles is known as post-herpetic neuralgia.
The postherpetic neuralgia may be treated with capsaicin ointment, 0.025–0.075%, or lidocaine (Lidoderm) topical patches.
Chronic postherpetic neuralgia may be relieved by regional blocks (
stellate ganglion, epidural, local infiltration, or
peripheral nerve), with or without
corticosteroids added to the injections.
Tricyclic antidepressants, such as
Amitriptyline orally as a single nightly dose, are the first-line therapy beyond simple analgesics.
Gabapentin, up to 3600 mg orally daily (starting at 300 mg orally three times daily), or
duloxetine, up to 60–120 mg orally daily (starting at 30–60 mg orally daily) may be added for additional pain relief.
Long-acting opioids may be appropriate.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Waqqas Shaheen, General & Family Physician
