Thank You Everyone for Responding - Very kind:
I suspect you are all right. I've so many aches & pains these days, that I'd forgotten that some days getting out of bed & those first few steps can be agonizing, but once mobile, I'm rarely bothered for the rest of the day or think about it, until the pain at night (but not
every night, which is strange!) Other things trouble me more during the day - a very pesky shoulder injury which never improves... but that's another post!
So any reliable remedies for preventing the intermittent night pain - not sure why some nights it's bad & others it isn't - should keep a foot diary I suppose!? But I'll do the research now...
Cheers, Tagohills
