Question

My grandfather was 72 years old suffering from extreme pain. At first he had bumps and then the runny like smallpox, but is limited to the left arm and chest. Grandpa suffered greatly because of this skin disorder that progressively widened. The bump's fluid also more numerous and some ruptured.

According to Grandpa, there are areas that are hot and painful bumps like watered chili. Grandpa Agency also slight fever that he could not sleep. Her appetite has also decreased, and every day he was forced open shirt as if it touched the skin disorder will dress agonizing.

I took Grandpa to the doctor. According to the doctor, my grandfather suffered from herpes zoster in the community known as smallpox snake. This disease will pass, but doctors give drugs for herpes, there is also a salve to speed healing. The drug is eaten five times a day and it is a dry skin disorder, but a trace.I look forward to the drying of skin disorders, suffering Grandpa will be lost. Apparently the pain caused by herpes continues to persist, and until now, it had been two weeks, Grandpa still suffer pain. If you can not stand, grandfather to scream in pain, especially if the disorder is touched.

Is it really such a terrible pain in herpes? Are there other diseases that accompany? Why herpes healed, but the pain still persists? What can be done to end the suffering grandfather? How to spread smallpox this snake? Could it be that this disease can be prevented, how?

Answer 
Varicella zoster virus

Shingles is a disease caused by the varicella zoster virus that gives skin rash. The rash will then evolve as smallpox and indeed this skin disorder cause pain. Shingles usually occurs due to reactivation of varicella zoster virus. So, someone who has been cured of varicella (chickenpox) can have herpes zoster.

In chickenpox, the aberration to the whole body, while on shingles in accordance with neural disorders so that only a certain part that gets the nerves are abnormal. Therefore, abnormalities are usually confined to specific areas and only half body. That is, the deformity is only on the right or left side of the body only. Indeed at the very decreased immune abnormalities may extend even to cross the rest of the body because the nerves that can attack more than one (multiple).

The typical symptoms of herpes zoster rash vesicular form (aqueous) with unilateral spread, spread limited to 1-3 dermatomes. The areas most commonly affected are the chest and arms while other areas may also be affected, such as the face. If herpes zoster attack involving the face and eyes, the pain may be more intense imaginable. In fact, if the disorder is not treated properly eye, it could potentially lead to blindness. 
Fever and muscle aches

Before any symptoms of the skin, usually in the form of preliminary symptoms of fever, weakness, and muscle and bone pain. After 4 to 14 days, then raised skin disorders. It is true that herpes zoster will disappear on their own. Administration of drugs (acyclovir) will speed healing. In young people, the healing may cause slight blackish scars form on the skin. However, in the elderly can occur post herpetic neuralgia. It is pain that occurs due to nerve stimulation and the pain is still there even though the skin had healed herpes.In the elderly, a longer healing period and the incidence of neuralgia is more common. Prevention of infection with the varicella vaccine is expected to prevent the onset of herpes zoster in addition to varicella disease. There is a cross-immunity between varicella and herpes zoster, but it seems not too strong cross immunity so for the elderly is now available shingles vaccine. 

The pain of post-herpes zoster may be reduced with antipain therapy. If the pain medication was also missing, you can ask the help of a doctor of neurology or neurosurgery to act on the nerves involved. So, I suggest you take your grandfather to a neurologist to overcome the pain that was very disturbing.
