Hi Mr. Dwivedi,
Welcome to HCM.
Your symptoms are suggestive of herpes zoster
. It is caused by a virus called Varicella
zoster. The infection is usually got when you would have suffered from chicken pox
(usually in childhood). This virus has a unique property of remaining in the body hidden for years. It gets reactivated only in few (5-15%) patients. The patients with stress
, exposure to heat, cold and any illness can cause this reactivation. This occurs in age group of 50 to 80 years, and whose immunity is very low. This episode of zoster usually lasts for 2-3 weeks but the pain will remain for few months. Please continue your treatment regularly and have a healthy diet. A repeat episode is unlikely but there is a vaccine
available called Zostavax which can be given to prevent further episodes. Get in touch with your GP for guidance regarding the same.
