Hello, this is Dr K.. Answers are not medical advice and do not constitute a doctor/patient relationship. I look forward to helping you today.
Unfortunately pain and nerve pain due to shingles often lasts several months.
In a small percentage of patients, it may go on longer. Hopefully this will not be the case.
Ask your Dr about increasing the dose of Gabapentin, this is a medication used to treat neuropathy and often Drs will not use a high enough dose. You may need to see a neurologist in consult
Use an ice pack also, this will help block the pain to the nerve endings.
Hope this helps
