Post Herpetic Neuralgia

Following an outbreak of shingles, there is a risk of developing a chronic pain condition known as post-herpetic neuralgia.  The risk is greater for those who are over 50, or who have a severe shingles outbreak.  If the original outbreak occurs on the face, the risk of post herpetic neuralgia is also greater.

Example of Shingles Rash


You can read more about shingles in two of my earlier posts:
1 )The Hearbreak of Shingles
2) New Drug Treatment on Horizon for Chronic Pain from Shingles


Post herpetic neuralgia occurs if the pain of the original shingles outbreak lingers after the rash and blisters have disappeared.  It is commonly described as a burning or tingling sensation; it often interferes with normal daily body functions, such as sleep or appetite.

It is important to see a doctor at the earliest signs of a shingles outbreak; getting a head start with antiviral medications is a good way to stay ahead of possible post herpetic neuralgia. (Note:The risk of developing this condition is reduced by half if antiviral therapy begins within 72 hours of the outbreak of rash!)

If you notice any of the following after the initial lesions have cleared, post herpetic neuralgia is a distinct possibility.  A follow up visit with your physician is in order!
  • Pain
  • Sensitivity to touch
  • Itching or numbness
  • Weakness or paralysis
If an individual is diagnosed with post herpetic neuralgia, the usual course of treatments are medications. Certain antidepressant and anti-convulsant medications can be used, along with topical lidocaine or capsaicin.

The best approach to this uncomfortable condition involves prevention.  If you notice a shingles outbreak on your body make every effort to see a doctor and initiate antiviral therapy within 3 days.

 The other preventive measure that is available at this time for persons age 60 and over is to consider immunization via shingles vaccine.  This is a personal decision; read about it and talk to your health care team about any questions or concerns you may have.

Living with Chronic pain hits the big screen!

Been to the movies lately?  Jennifer Aniston is on the big screen in a recent release titled "Cake." Her character, Claire is a victim of chronic pain...she belongs to a support group, where all of the members are coming to terms with the suicide of one of their members.  Of course, she also takes pain medication and addiction is another of her problems...and of course there's more! I guess I am writing this post just to bring readers' attention to the fact that Hollywood has become aware of the crisis that is chronic pain.  This movie is a testament to that. People that don't have to live with this kind of pain don't fully understand the whole story.  Maybe this movie will shed some light on the issues. Here is the official trailer for the movie: Sources: prweb;NorthJersey.com;YouTube

The Multimodal Approach to Pain Management

OK..so if you've been following this blog you will notice that there are a good number of ideas to help manage chronic pain.  You might ask yourself, "Which one of these ideas is best for me ?" I would suggest that you might try any number of these things, depending on your level of ability/disability, health care team recommendations, and your personal interests.  There are a number of reasons for doing this: 1) The patient is in control..with few exceptions, it is your decision what to try/not try and how many different things you want to experiment with at any time. 2) Non drug pain management ideas do not have any of the drug interactions or side effects that medications have.  You may have to set limits or modify activity according to personal circumstances, but usually it does not hurt to try any of them. 3)You usually do not need a prescription for most of the ideas I have described.  There are a few exceptions, such as physical therapy.  There ...

Beware Of The Tick!

It's tick season, everyone! And while we all know about Lyme Disease and its lingering effects, a new problem has entered the scene. According to the CDC, the Powassan virus is another tick-borne disease that has recently been recognized. The CDC says symptoms become apparent anywhere from one week to one month after infection. Symptoms include vomiting, weakness, confusion, loss of coordination, problems with speech and seizures. Approximately half of those infected by this virus have permanent neurological symptoms, which can include muscle wasting, problems with memory, and recurrent headaches. Many people who have been infected with Powassan virus required hospitalization and sometimes even respiratory support (i.e., a respirator). Treatment is focused on supportive measures. In the meantime, preventive measures are the best way to avoid Lyme disease, Powassan virus , or any other tick-borne virus.  You can read more about preventive measures by clicking here . Sour...
