Did they numb you first?????? Are you still in the hospital? Can you try to stick it out, it may be of great help to you.
If you are still in the hospital and the vas cath hurts you tell the staff. I can't tell from your post if it hurt placing it or if still in, does it hurt you? I hope to God if it was when they placed it, they gave you a local. Try to calm yourself, the stress isn't good for the M.G. I know it is hard. Have a nurse in the pheresis unit maybe go over everything with you. I hope you are doing better now. This is not easy. PS did a resident place the cath. I learned the hard way, have the interventional rad. place it. If the catheter is still in and it hurts, tell the staff.
