I was diagnosed with it, but have found it almost impossible to get treatment for it in my province so it's still a huge daily struggle that never really lets up.
It's really, really frustrating knowing help exists but I can't get it, be it therapy or medication. It actually makes me angry, I read stories of people whose lives have gotten so much better, but around every corner all I find are brick walls.
Winter tyres though and winter fuel mixes? Those definitely have an effect.
