@bionicartist I would first get a physician to tell you exactly what your prognosis is and than start your search.Othapedic issuses are not always correct by a tens unit, but and this is the million dollar question,can be if correctly used and placed.Do not buy a preprogrammed unit from anyone.Get a certified unit with adjustable pulse saturate that will be able to be set to your needs.Sorry the program ones only are effective for the faint.These are great with proper rehab and can ease the burden on going to another dr.
