I have found a hand held shower and hot and cold water used alongside massage to get the blood flowing helped a lot.
When I reacted badly to the AZ Covid jab - I thought it had done for me at one point, and my legs and feet were very swollen I was massaging my legs up to four times a day. When the swelling began to go down it was a great relief.
Since then I have had several run ins with cellulitis and incredibly painful feet, and odd sensation changes and found that massage helped there. These days I rub my toes with an antiseptic cream before and after cutting my toe nails just to try to avoid further incidents.
Despite all they've been through my feet are in good shape and sensation is normal, strong pulses when the nurse checked which is distinctly reassuring.
