I suffer from Raynaud’s Syndrome, which is a nerve spasm in my feet that restricts blood flow to my toes. The affected toes are a pasty white colour and feel cold and sort of numb. Sometimes a shower or hot water bath can fix the problem but what works best is a compression foot massager with a heating function.
Then it's a matter of choosing the compression type, intensity & heat (on or off) and letting it run for a 15-minute cycle. The top of the foot is heated while the sole & toe areas are alternately squeezed or pressed firmly then released before being applied again.
At the end of a 15 minute cycle the affected toes are initially still white but blood flow comes back quickly & they return to a healthy pink colour & the painful semi-numbness & coldness are banished once more.
