Back in March I had a lot of blood work done and my SED rate was 55 (normal is under 20). I had it done again a week later and it was 18. I just had another blood work-up done last week and now it is back up to 36. High SED rate can be caused by many things but it has got me worrying. I have vulvodynia (chronic vulvar irritation) so I am figuring that when I have a flare-up (which I am having now) that may cause it. Anyway, was wondering if any of you have SED rate issues and what has caused it. Thanks!
