The condition described is shingles, which is caused by the reactivation of the varicella-zoster virus that initially causes chickenpox. The virus infects the posterior root ganglia and causes a painful rash that follows the distribution of affected sensory nerves seen in their dermatomes. Myasthenia gravis is an autoimmune condition that affects the neuromuscular junction, causing muscle weakness. Neuronal damage is a general term that can refer to any injury or damage to neurons. Hodgkin's disease is a type of lymphoma, a cancer of the lymphatic system.
