Many thanks for the kind replies.
I got lucky to find about the shingles within 24 hours. The shingle rashes usually appears on shoulder, abdomen area or places that are hidden inside the clothes. My rashes appeared on the neck and were pretty bad, they were first spotted by my colleague during a meeting. I came out and just casually decided to see the doctor during lunch hour. At first sight, the doctor said it is shingles and its coming very bad. I started the antiviral right away. With all that, unfortunately after I recovered, I am feeling some symptoms again. I am on the watch. I think my problem relates to stress. I am trying to relax and taking lot of fresh fruit juices to boost up my immunity. The doctor asked me to keep an eye on rashes and if it recurs again, I have to restart the antiviral or be hospitalized and get them through IV.
Andy, anybody who had chickenpox in childhood is at risk of shingles. If you have not, then think about shingle vaccine. It is available for people at or over 50. I have 3 more years, but with the current episode I will talk to my doctor for getting vaccine.
Sharmin, The virus can be dangerous and can cause PHN which causes nerve pain for years and in some cases pain for life. I found there are people who lost eyesight and or pain medication for years.
Good news is that in most cases the virus can be suppressed but it never dies. Once you have Herpes Zoster virus (Shingle virus) due to chickenpox you have it and it continues to live in your spinal cord.
