My boyfriend fell skate boarding today. 33 yrs. old, 5 10 and 170 lbs. He has a high pain tolerance. When he fell he landed on his hand/wrist/forearm and was extreme pain. He said he couldn t even lift his arm to the stearing wheel when driving home. When he arrived he said he had cold chills. I iced the area for 20 minutes and made a sling so that it is elevated. When he lifted it to hold it so I could put the sling on he said he was really hot, felt like he might get sick. I felt him and he was sweaty and clammy. My thought is that he was in such pain that he felt like that because he might faint? What are your thoughts on the cold chills earlier and then later him feeling hot and sick?
