I am due to start Humira in a couple of weeks, once my hip surgery has recovered. I received a cooler bag and a diary in the post and I am a bit confused. As if it isn't worrying enough to have to start Humira in the first place I don't know why the diary only talks about my PSA symptoms and recording any scaley skin patches. Well I have been diagnosed with Inflammatory arthritis. Is this medication not for other conditions other than PSA?
