How long can PHN pain last?
How long does postherpetic neuralgia (PHN) last? Postherpetic neuralgia (PHN) can last for weeks, months, or in some people, years after the shingles rash goes away. In most people, shingles pain goes away in one to three months. However, in one in five people, pain lasts more than one year.
How can I stop PHN pain?
Anticonvulsants. Certain anti-seizure medications, including gabapentin (Gralise, Horizant, Neurontin) and pregabalin (Lyrica), can lessen the pain of postherpetic neuralgia. These medications stabilize abnormal electrical activity in your nervous system caused by injured nerves.
How long do you have pain after shingles?
Shingles typically causes a rash accompanied by pain in the affected area. The pain normally goes away when the rash goes away. This usually happens after two to four weeks. Pain that continues for longer is referred to as post-herpetic neuralgia.
Why is postherpetic neuralgia so painful?
Postherpetic neuralgia occurs if your nerve fibers are damaged during an outbreak of shingles. Damaged fibers can’t send messages from your skin to your brain as they normally do. Instead, the messages become confused and exaggerated, causing chronic, often excruciating pain that can last months — or even years.
What aggravates postherpetic neuralgia?
Diagnosis of Postherpetic Neuralgia (PHN) Additionally, the pain may have an itching, burning, sharp, stabbing or throbbing quality. Aggravating factors include light touch, such as the touch of clothing or standing in a shower. Relieving factors may include barriers to touch [1, 2].

How do I know if my nerves are healing?
How do I know the nerve is recovering? As your nerve recovers, the area the nerve supplies may feel quite unpleasant and tingly. This may be accompanied by an electric shock sensation at the level of the growing nerve fibres; the location of this sensation should move as the nerve heals and grows.
Is it painful when nerves are regenerating?
“The process of nerve regrowth can be extremely painful and if muscles have atrophied it requires a lot of physical therapy to regain function.
