It does not help anything and the stress it creates may actually impede your recovery. Instead, learn about the signs and symptoms of chickenpox complications and contact your doctor if they develop. Complications such as pneumonia and encephalitis are much more common among adults than children, but that does not mean every adult with chickenpox will have serious problems. Most healthy adults do not. The risks are greatest among people who have weakened immune systems or are pregnant.
Smoking also seems to increase the risk of complications.
Chickenpox is caused by the varicella virus, a form of herpes virus. Pneumonia associated with chickenpox is known as varicella pneumonia, because it occurs when the virus infects the lungs. Doctors cannot always diagnose pneumonia based on symptoms. A chest X-ray is usually needed to confirm the diagnosis. So do not worry, but do call your doctor and definitely see a doctor if you have not.
