It would not be wrong to say that the Tens units electrodes are a boon when it comes to muscle pains in the old age. Till a person gets in his middle age or crosses 60, he might be prone to diseases like Blood Pressure, Diabetes, etc. These come either hereditarily or due to old age. Keeping in view the other surrounding diseases, each time, a doctor cannot prescribe drugs. The history of the patient is important to be assessed. If things come to the fore then the doctors cannot prescribe any sort of a drug. This is where Tens units electrodes seem more like a godsend. And why only old men, Tens units electrodes are a stroke of luck for us all.
