Hi, yesterday I had really strong chills and my fingertips got numb for about 3 hours. My nails were a little blue and I was really cold. I put my hand in hot water, and put many layers on, but nothing worked, My body did not get warm. After about 3 hours all the symptoms went away and I got a fever that went up to 39.5 celcius. I took a tylenol and the fever got better. Last night the fever went up again but I took a tylenol and it got better, and today I do not have a fever. The same thing happened like 4 months ago. I am worried about the numbness on my fingers and that it happened once before with the same symptoms. What could it be? I am breasfeeding. Thanks!
