I have suffered with severe arthritis for as long as I can remember. I have also been diagnosed with every kind of arthritis and have recently been diagnosed with psoriatic arthritis. My symptoms fit the bill perfectly and I agree for once with the diagnosis. My question is how effective is Stelara for arthritis? I can see that it has worked wonders for those with Psoriasis but not much on arthritis. I do NOT have any psoriasis on my skin just the arthritis. Any feedback would be great!!
