Special soap cleaned the skin, but only time will get under the nails.
Piriformis has been acting up in spite of stretching and acupuncture and physio, so today I had a massage. Hadn't intended for it to be shiatsu, but I got a Japanese masseuse and a very shiatsu-type half hour. Shall see if there's fall-out from this (have I told you my shiatsu in Japan story?) but have booked another session plus acupuncture for next week. Piriformis has of course tightened up again.
