sedentary life style. This life style along with the progression of the Leprosy infection will weaken Sannu’s muscles. A feature common to all forms of Leprosy is nerve infection. Nerve damage appears to result from the multiplication of bacilli within Schwann cells and damage to the perineurium. Most of the deformities occurring from Leprosy are in fact due to trauma or a secondary infection. In a Leprosy infection one of the first symptoms are anesthesia to heat and cold. Leprosy affects the peripheral
