[The Thing] The Thing grabs my arm and starts to take over my body, what would I feel? If anything?

Pain? Am I even right in assuming it CAN "take over" my body?

hard to say, the doctor is taken over seemingly without him knowing, he goes into cardiact arrest either by the stress of the situation or the stress the thing is causeing his body. 
In the prequel we see one character become fussed to the thing, he was screaming a lot but that could have been the horror of the situation.
