TENS, transcutaneous electrical nerve stimulation can be done in a doctor’s office, physiotherapy clinic or even at home if you have been instructed how to use it correctly.
Like all medical treatments, there are a few disadvantages to TENS as a pain therapy. First, it isn’t known if TENS should be used on pregnant women. There hasn’t been any definitive research into if it can cause damage to the fetus. Some people develop skin irritation to the area where the TENS is applied and, if you have a pacemaker, you should check with your doctor first before trying this type of treatment.
