What Causes Cold, Coughing With Feet Coldness And Sweating?

I have a really bad cold, and I didn't sleep all night because of excessive coughing. On the average day, my feet are always cold. However, last night they were sweating excessively and I have no idea why, especially since I didn't have a fever. I just want to make sure its a normal symptom for a cold because my feet never sweat. Any thoughts?
