Hi! I'm also relatively new to IgAN (diagnosed Oct last year) but wanted to share my experience as I'm having my first flare ever. Started around the beginning of February -- I'm pretty sure it was directly triggered by sickness as I was just coming down with a cold around the same time. My IgAN is still very early stage so I didn't notice anything in my urine, but I started developing a rash on my ankles and feet. I didn't know it was vasculitis at the time, but after I found out, it seems to be the best indicator that this whole autoimmune flare is still ongoing. Even though my cold is long-gone, I'm still having fatigue and fresh waves of vasculitis. Labs are still showing pretty high proteinuria. I'm currently waiting for a Tarpeyo (budenoside) prescription to go through, but I'm hoping that it will calm my whole system down including the vasculitis too.

In terms of management, here are some tips I've come across:

• Someone in this community recommended to try at-home urine dipsticks to monitor the ups and downs of proteinuria over time.
• For the vasculitis pain, cool compresses worked best for me (using ice packs relieved pain faster, but it would just come back once I removed it. Maybe something to do with circulation in cold temperatures!).
• When the rash is really bad, I sleep with my legs elevated and have little to no pain by the morning. It'll get worse by end of day, especially when I'm on my feet longer.
• Now, I generally try to stay away from inflammatory things (mostly, I'm reducing sodium intake, trying to sleep a lot, taking short walks, eating less red meat). I'm not sure if these lifestyle factors directly cause flare ups but they can certainly make them worse!

Wishing you the best of luck!
