Thanks. I tried it again with less hot water so that it was warmer than mid warm (just warm feels like icy cold to me and is unbearable--our house if very cold) but had the same results--more pain than usual at bedtime. I also noted that after my infrared sauna 2 days ago my pain was worse, so it does seem that heating up my feet before bedtime worsens my PN. I'm trying different topical applications and am having some success with that.
