Home / Frequently Asked Questions

Who should use the FlexDoctor?  

FlexDoctor is ideal for people who are looking for non-invasive pain relief from neuropathy. This can include diabetes, injuries, acute pain, or chronic pain. FlexDoctor is also capable of increasing flexibility and extending range of motion. 

Who cannot use the FlexDoctor?  

Pregnant women cannot use FlexDoctor. People who have a pacemaker, ICD, or any other electrical implanted device cannot use FlexDoctor. 

How exactly does the FlexDoctor work?

FlexDoctor delivers a compound double exponential electrical wave form that is harmonious with the body. Rather than trying to block pain signals like other devices, this patented technology overrides the signal and is better received by the body.

How often should I use FlexDoctor? 

Whenever you are in pain, simply turn on the device and place the pads as you have been instructed.

How quickly does the FlexDoctor change my pain?

The average patient sees a change in less than a minute.

How long does the pain relief last?

Typically, patients report relief of 45 minutes to 4 hours after a short application.

If my main problems occur during the night, is it OK to sleep with the FlexDoctor?

Yes.  You should have a peaceful night of sleep.

Can I use FlexDoctor when it is charging? 

No. You must have the unit charged in order to use it.  However, you should be able to get hours of use off of a single charge.

Does FlexDoctor have any side effects?  

You may experience soreness if you use FlexDoctor at high intensity. You may feel your muscles contracting if you use FlexDoctor at high intensity. Neither of these are dangerous.

At a high intensity electrodes may cause redness on sensitive skin which normally fades shortly after use. You are more likely to receive adverse effects from electrodes if they are not placed properly or if the electrodes are too old.  Do not use low quality electrodes.

What if my FlexDoctor does not power on?  

Please ensure you are holding the power button for at least three seconds. If the unit does not power on after that, the battery is likely discharged. Please charge the battery.

What if the sensation from the electrodes is intermittent? 

This likely means that there is a loose cable. Check to make sure the cable is fully inserted into FlexDoctor as well as both electrodes. 

What happens if the FlexDoctor shuts off while I am using it?  

The battery is likely discharged. Plug the FlexDoctor into the charger. 

How do I care for my electrodes? 

To care for your electrodes, use them as intended. Make sure you put them back on the protective sheet after each use and place them back in their bag. Avoid using them on oily skin. Avoid storing them in a warm, humid space. When the gel on the electrode starts to wear off it is time to replace them. Electrodes typically last for around 20 uses. 

What should I do if my electrodes lose their stickiness? 

If the electrodes begin losing adhesion, gently rubbing one or two drops of water onto the gel surface and cleaning them may extend usage. If not, replace with new electrodes. Do not use low quality electrodes.

How high should I turn the power?  

 Turn the FlexDoctor up until the sensation from the device overrides the pain you are experiencing.

Is FlexDoctor safe?

FlexDoctor is a Class II FDA cleared device and is safe as long as it is used as intended. FlexDoctor is a nonsurgical, scientifically proven device designed to relieve pain.
