Help

I have ulcerative colitis and started Humira. I was on it for 3 rounds and I immediately started having swelling in my extremities. My GI dr. stopped the Humira because the swelling and then the pain started. I have been off the Humira for almost 3 weeks now and I am in severe pain all over, especially in my joints. My GI dr. referred me to a Rheumatologist and I am waiting for the appt. My GI Dr. said the Humira would not cause this kind of pain. It is debilitating, I cannot hardly get in and out of bed. Severe pain. Does anyone have any advice on if this is from Humira or do I possibly have RA? The pain was sudden and I have to go back to work on Monday after Spring break and I don't know how I am going to even go to work, it hurts that much. Does RA just hit you like that? All suddenly? It hurts so much!

Yes, like I said, I took the Humira and I have all of the side effects, but no disrespect, but that doesn't answer my questions. My questions aren't so much about Humira, but about RA. Thanks though
