3) Common symptoms of Multiple sclerosis are - Vision problem occurs due to inflammation of optic nerve that damages the central vision. Sensation of numbness and tingling as the signals across the nerves are confused and are not transmitted completely or effectively. Weakness and Muscle fatigue due to degeneration of nerves. Vertigo and dizziness occur due to lack of coordination. Schwann cell is responsible for insulating axons in Peripheral nervous system. It is not affected in Multiple sclerosis. It is oligodendrocytes which are affected, and thus fail to insulate axons of central nervous system. 4) Lidocaine prevents the evolution of action potential and thus decreases or stops any sensation arising in affected area.
