Answer
: Hello Patricia. Shingles is a very painful and often debilitating condition. It is caused by the same virus (herpes zoster) as chickenpox. After one contracts chicken pox, the virus can lie dormant in sensory (skin) nerves for decades. It reappears when the immune system is weakened by age, disease or unmanaged stress. When events occur that decrease the immune system, such as aging, severe emotional stress, severe illness, or long-term usage of corticosteroids, the immune system cannot suppress the dormant organisms any longer and they become active again, causing infection along the pathway of the nerve.
