It is due to your body repsonse against foreign particle. Anything entering in body is foreign particle and body has its immune system to fight against it. the Response of immune cells to foreign particle produces lots of heat in the body termed as fever.

Question: As a child did you ever run a really high temp? My brother ran a sudden high fever(cause never found, of 105 and soaring)that nearly killed him. He was wrapped in towels and buried in a tub of ice to bring the fever down. But while waiting on the ice to be brought he was bathed from head to toe in rubbing alchol. At that time the doctor did the only things he knew to do. The fever came down but my brothers normal temp of 98.6 was changed to 96.0. So a temp of 99.0 is not low grade fever anymore; at least not for him.  Are you under great amounts of stress? Stress can do wild things to your body. Under tremendos stress  the muscles literally separated from the bones in my chest area. Doctor's at first thought it was a heart attack but my pulse did not indicate such to be the case. I felt as if a huge weight had been droped on my chest, but it was stress. Vicatin would not even allow my body any relief, and the doctors had said if it didn't help that morphine was the next step.Fianlly, after several months of just letting nature run its course; I finally stopped hollering with every breath. I would shake like I was in a ice house on min. and feel normal the next; but my temp. was up and down like a yoyo. Do you have any other symptoms, coughing, sneezing,dizzy spells, black outs, nausea? Have you been to a doctor yet? If not; I strongly reccommend you go see one immediately. Keep in mind not all diseases or illness's cause the same reaction in a person. You can take 50 people with the flu. Some it turns into more upper respitory infections, and some of those can be fatal. Others just feel crappy and tired. While some can't see much difference in the flu and what most people would call a bad cold. My temp. runs 98.6; 99.0 is low grade, and any thing more than 102.6 I start calling the doctor. As I said I strongly reccomend you go straight to a doctor and have them check you out. I wish you well.

According to my professors in medical school the critical point to start treating fever is 103 farenheit.  Otherwise, it is safe to let it burn.  You see, this is one way to let the body take some of the resources that the pathogen would like to use, out of their hands.  Enzymes denature at higher temperatures...enzymes that the bacteria or viruses use to reproduce or create toxins.\n\nIf you decide to treat your fever you should use the classic anti-pyretics (anti-fever).  Tylenol for instance.  Dont use too much.  Monitor your fever and if it gets too high then go to the emergency room.

You sweat. \n\nYour dog pants. \n\nYou can buy commercial evaporative coolers. \n\nKids cool off in the summer by running through a sprinkler. \n\nPut a cold compress on your head and feel it cooling your fever.

No one can diagnose you without a physical exam and possibly some testing.  Please call your doctor first thing in the morning and make an  appointment.  Until then, take tylenol  or ibuprofen for the fever in addition to drinking a lot of fluids.

Take her to the doctor asap. I was swarmed by fireants at a young age and the same thing happened to me...high fever, vomiting, etc. I was poisoned. I ended up being admitted to the hospital overnight. I wish I could give you more details, but I was so young, all I remember is how sick it made me and how bad it hurt. It can be a big deal, so, please, get your baby looked at! Good luck and I am so sorry for you and that little punkin!!!!

The most common cause of high potassium (hyperkalemia) is impaired kidney function. Other causes of hyperkalemia include:\nCertain medications, such as angiotensin-converting enzyme (ACE) inhibitors \nHormone deficiencies, including adrenal failure (Addison's disease) \nDestruction of red blood cells due to severe injury or burns \nExcessive use of potassium supplements \nSometimes a report of high blood potassium isn't true hyperkalemia. Instead it may be caused by the rupture of red blood cells in the blood sample during or shortly after drawing the sample. The ruptured cells leak their potassium into the serum. This falsely elevates the amount of potassium in the blood sample, even though the potassium level in your body is actually normal.

These are all good answers. The one thing that I find useful when thinking about this is that body temperature is tightly controlled around specific target temperatures, or set points, like a thermostat controls room temperature. Fever is an adjustment upward of the set point. The control is still there, the target temperature has just been elevated. In some instances, the set point can be raised too high, or control seems to be lost, but generally the body manages the response well.

Your fever is your body fighting the infection. It raises it's temperature to kill the bacteria. When you feel cold, it's your body reacting to your fever trying to cool you down by giving you chills so you won't be uncomfortabley hot.

Cold extremeties are most often caused by poor circulation. Try doing light exercise or stretching to get your blood pumping. This can also be a sign of something more serious like hypoglycemia... so if you're having any other unnatural symptoms, talk to your doctor.

Cotton fever is probably not caused by cotton fibers. It's more likely caused by bacteria that live in the cotton. Cotton can grow a lot of bacteria, especially after it gets wet. Re-using cottons can put bacteria directly into your blood stream. Cotton fever is uncomfortable, but it's usually not serious.\n\nSymptoms may include:\n Chills\n Headaches\n Fever\n Nausea \n Hot flashes\n Vomiting \n Shaking that you can't control  \n Shortness of breath

You could raise your internal temperature by dressing in heavy clothes, but your internal thermometer will remain normal - and you will sweat in an effort to maintain a normal temp.  \n\nOn the other hand when you are ill your body resets its temperature (thought to be a defensive mechanism to help fight infection several ways).  In that case you can bundle up and sometimes are still feeling chilled.  What happens when you break a fever...you sweat, cooling your body, bringing it back to normal temp.
