New brunswick canada symptoms and conditions

I have had 1 remicade infusion so far for ulcerative colitis. The next day a bunch of spots appeared on my lower legs. There were 30-40 of them, small, roundish, purple/dark red. They looked like blood spots under the skin.
It wasn't a rash and they didn't itch or hurt. My doc had no explanation, and I haven't heard of anyone else having this reaction. They checked my blood for a clotting problem and didn't find anything. The spots faded away over a week or so. My next infusion is in 2 days, so we'll see if they reappear.
I have also been experiencing a weird kind of insomnia where I am so physically antsy I CANNOT keep lying still, I have to shake my body or kick my legs or something. I read up on restless legs syndrome and the symptoms sure sound like what I am experiencing. I don't know if it's connected to the Remicade - I read that iron deficiency can also cause it and I am anemic due to the UC. But since Remicade can disturb the central nervous syndrome, it seems possible. Anyone else experience RLS with Remicade?
