One of you recommended Therapulse so I ordered one..£42 inc. P& P.. It is an attachment on one leg that sends an electric pulse at varying speeds for 10 minutes or longer.
I was sceptical as the foot plate didn't work for me that I bought years ago that also vibrated etc..But so far Therapulse is working. I used it on each calf twice yesterday...lunch time and evening when my RLS started.
I have no financial interest in the company but it does seem to be working.
