Sciatica is pain caused by irritation of the sciatic nerve. The irritated nerve causes pain that runs down your leg from your lower back or hip. The sciatic nerve is formed by a group of nerves that run from the lower spine down the leg to the foot. Anything that irritates the nerve can cause sciatica.
List of Air Borne Diseases Photo Credit Jupiterimages/Comstock/Getty Images. A disease is classified as airborne when respiratory droplets from one person can easily contaminate the next person.

Squirrel Diseases: Squirrels are typically not important vectors of disease-I don't think there's any documented cases of rabies transmission from squirrels, for example. Like all animals, squirrels can carry parasites, they leave behind excrement, and they can leave both in your attic.oonotic Diseases: Zoonotic diseases are diseases that are transferred from animals to people. While common sense can often prevent transmission of many diseases, others, such as those transferred through contamination from animal waste, are harder to avoid.
