small update. Even tho i'm just starting the ultrasound and dr. hos' foot pads /tens units..........in this very short time.........i only used the ultrasound maybe 3 times each foot. i really thought it was helping reduce the stiffness in my feet. Didn't want to say that, because i thought it might be wishful thinking. However, last night and twice today, i used Dr' Ho's foot pads. altho i did like the sensation going up thu my legs, ....thinking....it was working well, ........it appears, that my feet are tighter then before..........oh crap!!! just wanted to note that to make sure you don't rush out and get a tens unit, yet, anyway. from TensPro, it was only $35.....but Dr; ho has foot pads which i thought would really be great.......maybe it still might help my legs, if i use it on them...........something i will have to tinker around with. But, since the ultrasound seemed to be helping the bottom of my feet.........tomorrow morning i will be going back to using it, one day on the right foot, next day on the left, then 2 days off, and then alternating the feet again............I also can't hardly cross my legs over each other. One leg i can a little, the other , not so much, so that also will be something i can see if there is a difference or not. I told a couple of chiropractors, ....i'm 82, and when i can hop, jump and skip around dancing to Footloose, which i really liked to do.........then...........i will consider myself healed!..........just wanted to point out the disappointment in the foot pads....so far, anyway.
