Thanks so much Nanny! Ugh.. I'm just miserable!!! I have been having more flares sine my IVIG insurance mess up in January.. It's like I just can't get on top of it

I do have some petechiae and I also get hematuria (microscopic)... and awful nerve and joint pain and fatigue.. My joints have even been swelling up and some of them don't ever go down.. like some sort of erosive arthritis :(

My WBC count is down to 2,9 as well... so not sure when I need to get on steriods or do something else.. I'm finding it hard to function - work, kids, house and so on!

Hello and yes I also suffer from vasculitis and unfortunately not much is medically known about it as it is so very rare. What helped me a lot is to observe my own body and then I realized that stress is a huge component to cause vasculitis-flare-ups. Since realizing this I have observed my body to learn as much as possible ot try and avoid stressful situations. That included (for me personally) to even avoid people who cuased me flare-ups in the past as they were aggravating me too much and my flare-ups were not "worth it" for me to put up with this aggravation any longer. Since making this very drastic decision I am doing so much better medically speaking.
I send you my best wishes and please be rest-assured that I understand how difficult i is ton many occassions to deal with vasculitis as a patient..
Best wishes for you to succeed from Kristina.

A form of vasculitis is a best friend of mine at the best of times. It's one way that I can tell it's time to pull back fr life a bit, it's my warning. I get the reddish spotty rash mainly on my legs & sometimes the arms. My legs get itchy at times also. I find as long as I pull back fr life, be extra nice to myself it usually backs off also. I find I use Gold Bond itch lotion & that helps alot too.

Thank y'all so much.. ugh.. it is so frustrating, as I have always been a Type A.. on the Go person... so this just makes me come to a screeching halt.. but with a job and kids, it's hard to limit enough stress!!

I started a new job, and that first week is when I got ulcers - on my scalp, mouth and inside my hose (ick).. rash, crazy joint swelling and aches.. muscle weakness, low grade temp and just all over ickiness.. my joints feel like there is glass in them, its almost dibilitating.. and it's for sure Frustrating, as I don't have time to sit around, and I need to be able to grip things, and move better than a 90 year old!

I have been taking my baby asprin again.. which i feel like helps.. I have been on plaquenil for 5 years... do they have increase the dose again, like they did in the beginning??? I feel like i need to up my levels again or something.. I worry I"m doing permanent damage (blood in my urine, joints getting deformed, even the chest pain returns during these flares.. and pleurisy.. which is different than my other chest pain).. blah!
