@suzanne2 - I bought an inexpensive hot/cold Wahls massager on Amazon and still have it although I don't use it much. At the time I bought it, I thought it might help with the numbness in my feet and used it extensively every day for a few weeks but it really didn't help. It did make the feet feel a little better during the time I was using it. The one I got was an older version of this one - https://www.amazon.com/Electric-Massager-Relaxation-Professionals-04295-400/dp/B00MTKBH1U/ref=sr_1_5
