Hi Sarah,
You're not alone!! I had a horrible time with sweating for a few months, especially round my head and face, but it's gone again. It seems to come and go. We're not known for our hot weather in Scotland, so I can't blame it on that.
I also get the nail changes which Pete mentioned, rapid growth for a few weeks, then nothing. I don't mind that so much, I've always had short nails so it's nice to have them long for a change. Unfortunately, it's only on my RSD hand so I look a bit odd.
Hope you're ok, I'm sorry that doesn't help much. Take care.
