If you do chances are good that the ârotten eggâ smell or sulfurous smell is caused by anaerobic bacteria setting up quarters in the magnesium and aluminum elements of your water heater, creating gas.
Reference from A.D.A.M. Neurological deficits - focal. A focal neurologic problem can affect any of these functions: Movement changes including paralysis, weakness, loss of muscle control, increased muscle tone, loss of muscle tone, or movements a person cannot control (involuntary movements, such as tremor)
Neurological conditions: muscle weakness can be caused by cerebrovascular disease such as stroke and brain haemorrhage and spinal injury. Muscles which become partially or completely paralysed lose their normal strength and will eventually waste. Some recovery is possible but it will be slow and may not be complete.
