Persistently elevated ESR/CRP but no diagnosis yet—any similar experiences?
Hi everyone,
I’m (32 F) feeling really lost and was wondering if anyone has gone through something similar or has any advice on what path to explore next.
This doesn’t include my entire medical history but about 6 months ago, I had a pretty dramatic decline in my health. I developed lower back, hip, and leg pain along with morning stiffness. If I overdo it, I often end up feeling like I have the flu with fatigue, headaches, muscle aches, feeling feverish (usually without an actual fever), and my lower body feels incredibly heavy, achy, and stiff. Gentle movement helps a little, but too much activity also makes things worse.
I was referred to rheumatology because my mom has rheumatoid arthritis which primarily affects her lower body, so they thought maybe I was developing something similar.
But most of my AVISE panel came back normal. However, I have a positive ANA, persistently elevated ESR and CRP that continue to rise, an elevated white blood cell count, and an elevated fecal calprotectin (420)
Because of those inflammatory markers, my rheumatologist initially suspected inflammatory bowel disease with extra-intestinal manifestations. I’ve had ongoing GI issues since an emergency gallbladder removal in 2024, but these newer symptoms are what have significantly changed my quality of life. I’ve now had a colonoscopy with biopsies and a capsule endoscopy, and both were normal.
Ankylosing spondylitis was also considered but I’m HLA-B27 negative, and my MRI didn’t show anything that explained my symptoms.
At this point, I’m just so confused. I don’t understand how I can have persistently elevated inflammatory markers while every test seems to come back normal.
I’ve lost a lot of my normal function and only work part-time now because I never know when I’m going to trigger more symptoms. The only things that have consistently helped are naproxen/celecoxib, and a short steroid taper.
Has anyone had a similar experience where it took a long time to get a diagnosis? Were there any conditions your rheumatologist eventually considered that weren’t
obvious at first?
I’m just wondering if anyone has been through a similar diagnostic journey or has suggestions for what I should discuss with my rheumatologist next because I see her next week.
Thank you!
