Ohhh I hate that I mainly wear shorts or trousers to avoid it.

Don't know if you know this or not but I found the best thing to heal the legs quickly is baby oil, when mine get chaffed I put loads of oil on when I go to bed and by morning my legs are fine again. I had been told to use talcum powder but found that just dried my legs out and caused scabbing which was even more painful.
