hi my daughter complained over the summer wih itchy feet. she hd little white spots on the sole of her feet. they to me loked like little sweat spots and I wdvised her to stop wearing socks in bed aand let air at them. however she has come down from bed tnight complaining her feet aare sore and she cant sleep. ive checked them gain and these soft stops that were previously there remain however they are hard to touch and plain white in colour. any advise would b great. louise
