For about 10 days now I have been experiencing headaches, chills, numbness/tingling, fatigue. My body feels very weak. I have been having an uncomfortable, ongoing tingling sensation everywhere. I also having been experiencing the chills that make me shiver nonstop. I either feel freezing all the time, or very hot, to the point where I cannot sleep even without clothes or covers on me. I experience nothing in between the two, it s either freezing to death or burning to death. With my body feeling this way, my appetite has decreased immensely. I have had a hard time distinguishing when I have hunger since I have don t feel hunger pains. I ve also been getting really bad headaches, a few of which have been terrible migraines. From what I have been told, I have been having tension headaches, (these began the same time I started feeling sick), which I m not really sure If it s correlated with my other health conditions. No signs of congestion, coughing, or a sore throat. I am just wondering if I should get any tests done, such as blood test maybe? My symptoms have been getting worse and I am just a bit worried that I have an infection or disease that I do not know about.
