Have you seen a dermatologist about the scalp sores? I'm wondering if it could be psoriasis -- it's hard to tell from your description, but the timing is a bit suspect. Do the scabs have a silvery look to them? Psoriasis tends to flare with Crohn's and there can be a rebound effect when stopping steriods.
