I usually use my tens unit for 2-5 hours. It does work for my larger body pains like shoulders, neck, thighs. I'd rather use the tens than popping more pills.

I love mine. But I tend to leave it on. It helps so much I don't want to let it go off

Hi Kaye ... I've Used A 'Tens Machine' For Years And I Do Find That It Helps Quite A Lot At Times ... I Do Agree With Marylou, Not To Use It During A 'Flair' But Rather, For Use In Specific Areas That Are, Either Giving You The Most 'Pain' All Of The Time Or, Occasionally Too... You Can 'Move' It Around Accordingly And A 'Good Quality' Tens Machine, Will Have A Power Level - To Incresae / Decrease The 'Stimulation' Of 'Electric-Shocks' That Go Through The Area " ⬇️ " And It Definitely Should Have A 'Timer', That You Can Set, So It 'Switches-Off' Automatically, Then You Don't Have To Worry That It's Left On For Too 'Long' ... I Got Mine From My GP And I Would Suggest, That You 'Try' There 'First', However If You Can't Get One That Way, Then There Are Good Ones On The Internet Or, If You Have A 'Boots' Pharmacist's Near You, They Sell Really Good Quality Ones Too ... Please, Make Sure, That It Has The Power Level Component, Plus The Automatic, 'Shut-Off' Timing Control Because, These Are Really Important / Safety Features ... I Usually Use Mine For 45 / 60 Minutes At A Time - In One Area (Sometimes A Little Longer) Then, I'll Move It To A Different Area, If Needed ... However, Everybody Is Different And Can Withstand The 'Sensation' For Shorter / Longer Time - Depending Upon The 'Power-Level' Setting ... I Really Hope, This Has Helped And If You Need To Talk Or, Just Want To, Im Hear Anytime Which, Goes For 'Anybody' Else Too ... Much Love N Big, Yesterday Soft Gentle Hugs Your Way, Today And Everyday ... Trish xx❤️

I do have a tens. But let me warn you kaytussing . You won't be able to use it during a flareup. What it does is send shock waves through your skin (ie nerves, muscles, tendons) at the spot of placement . Well..... what is fibro ? A nerve ending overload. See what I mean ?

Tens unit made me hurt more,but everybody is diffetent.
