Headache after angiogram

Hi, I had my first angiogram last Wednesday which seemed to go OK. Since then I've developed a 'new' visual disturbance and have had a headache since Sunday. My headache got worse on Tuesday - i'm not sure if this was due to the stiffness and pain in my neck that had appeared. Oh, and the pulsatile tinnitus is back. So basically feeling pretty sorry for myself today. [Don't worry I'll get over it :-) ]

Are these things normal? Should I be concerned? What did other people experience after their angiograms?
