I have been using epsom salts topically last few weeks. Dissolved in hot water then left on face for a minute or so in shower.
My erythromelalgia has also been worsening during this time which has led to broken/worse quality sleep.
Could be coincidental but i'm sure i have made this association before.
Probably coincidental and other possible factors such as weird weather etc but with breakouts continuing pointless carrying on. Seems unlikely i will never get through my shit load of epsom salts now.
