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)
To the patient and the doctor it often looks as if there has been a stroke or have symptoms of multiple sclerosis. However, unlike these conditions, with functional weakness there is no permanent damage to the nervous system which means that it can get better or even go away completely. The diagnosis should usually be made by a consultant neurologist so that other neurological causes can be excluded.
