Hello, I am a man in my 50s.
I don't have any illness that I am aware of, except maybe some IBS. I also don't drink, don't smoke. And don't exercise except for some Tai Chi in the morning. But I do generally feel cold and require a higher temperature in the house than everybody else in my family.
Yesterday evening, after dinner, I accidentally dropped a piece of furniture on my foot. Apart from the intense pain, my body reacted in the most bizarre way. I started to shiver, feeling chills and cold. The shivers were intense, uncontrollable. I don't remember having anything this strong ever. I wrapped myself in an extra blanket and went to bed. With the extra warm they went away. Now, 6 hours later, the symptoms are all gone. And even the foot shows no sign.
I am curious to know what could have caused the reaction. I checked online, but all I could find are articles about chills and shivers after a head blow. But in this case, the head was unaffected.
