What is Shingles?
Shingles is a viral infection that is caused by the reactivation of the chickenpox virus. It causes a painful blistering rash that may be seen as a stripe or belt-like pattern along one side of the body or face.
Phases of shingles:
Caution must be taken during the blister phase. This is when the virus is contagious and may spread. Therefore, be sure to cover the rash, avoid touching or scratching the rash and wash your hands regularly.
On some occasions the pain may still be there even after the rash heals. If the pain lasts for more than 3
months, this is called post-herpetic neuralgia (PHN). One in five people with shingles may develop PHN.
Signs and symptoms of PHN may include sensitivity to light touch, itching and numbness. These symptoms
may be eased with painkillers such as panadol or nurofen or your doctor may prescribe you with a nerve
medication called lyrica.
Risk factors for developing PHN include severity of shingles, age (50+), chronic illnesses, shingles location and if treatment was delayed for more than 72 hours after the rash has appeared. However, if shingles is diagnosed early enough (within three days of the rash appearing), it can be treated with antiviral medication prescribed by your doctor.
