Thanks for your question on Healthcare Magic. I can understand your concern. By your history and description, possibility of post shingles neuralgia is more likely. It is due to nerve damage. Best treatment for this is pregabalin or gabapentin. It is available in combination with vitamin b 12. So take this combination twice daily for 10 days. Apply ice packs on affected areas of body. Don t worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
