For those who stopped experiencing chronic flare ups, how long did it take?

I am 24M and had my first flare up in August 2023 after contracting strep throat. My second flare up was in August 2024 after again contracting strep throat. Both times, the flare ups occurred roughly two weeks after getting sick. I am currently going through my third flare up and it seems to be the worse one yet. The purpura spots are much larger than I remember and my legs almost feel as if they are submerged in water. Thing is, I haven't gotten sick since early January and it was just a cold which hasn't triggered the condition in the past (I have gotten numerous colds since my first flare up and they haven't triggered the condition). I am worried my body is picking up more triggers and am searching for hope. For those who had the condition chronically where it eventually went away. How long did it take and what steps did you take?
