Biologics in general can unmasked other conditions that share the same genes
Such as psoarsis and spondyloarthritis and Crohns
The genes and pathways overlap a lot
So the med doesn't cause the disease per say
That said strongly recommend you see a rheumatologist
While you may have joint pain /inflammation while on humira
There are things that can be done to fix it
A rheumatologist can help you figure that out
Spondyloarthritis (SpA)can be directly related to your gut inflammation so if your Crohns is mildly flaring your joints flare
OR
SpA can run independent of your gut
So your Crohns could have no inflammation and your joints still be a mess
Ds has JSpA which was dx while on humira
He was recently off his humira for another reason
While his Crohns was mostly calm his arthritis was significantly flared
Once he started humira again his arthritis has started to calm down
He did have to increase his humira dose and mtx when dx with JSPA
That has helped to control the arthritis
