Signs and Symptoms of Chills Without Fever

Some of the most common signs of chills without fever are listed below:

  • Shivering – When your body is suddenly exposed to a cold environment, the body will produce heat through muscle contraction to increase the body’s internal temperature. Shaking is often accompanied by chattering teeth.

  • Goosebumps – Both fear and cold can cause goosebumps on the skin.

17 Common Causes for Chills Without Fever

With all of these things in mind, it will be easier for you to determine the leading cause of chills without fever.

1. Hypoglycemia

Hypoglycemia refers to the sugar level in the body being so low that the body cannot work correctly. People who suffer from this condition normally have diabetes. One of the most common symptoms of this condition is experiencing chills without fever. When your body’s sugar level is very low, it will not function correctly.

Hypoglycemia can cause chills without a fever. Other symptoms of hypoglycemia include dizziness, cold sweats, hunger, rapid heartbeat, headaches, sweating, anxiety, and dizziness.

If you feel this condition is the leading cause of your chills, you need to drink something sweet. This can be the temporary fix you need to eliminate the chills. Eating something sweet when you have diabetes may not be the best option. You may take something safer, like apple cider vinegar, to give you the needed sugar without the possible complications.

2. Side Effects of Drugs

Prolonged use of medications such as ibuprofen, Effexor, Voltaren, and ondansetron may cause side effects like chills without fever. Sometimes, an intense cold may be caused by Narcotic painkillers or drugs like beta interferons.

Make sure to read the medication packaging to learn potential side effects information. If you suspect that the drug is the cause of your shivering, you should consult your doctor immediately.

3. Cystitis or Urinary Tract Infection

Cystitis or Urinary Tract Infection may be the primary reason you have chills, but you do not have any fever. When bacteria get into your urethra, the infection may turn more severe. Women are more likely to experience this infection than men.

When you try to urinate, you may feel that it is painful. There are instances when you are unable to urinate at all. In addition, other common symptoms include:

  • Urinating frequently: Cystitis can cause a full bladder feeling, making you go to the bathroom many times. However, there is not much urine every time.
  • Smelly and bloody urine: In cystitis, it can cause a cloudy and strong bad urine smell. Sometimes you may notice blood in the urine. This is because inflammation causes a bladder infection that reaches the kidneys and causes red blood cells to enter the bladder.

If you get a bladder infection, the first thing you need to do is to have yourself checked by the doctor. You would have to prevent the disease from spreading to your kidneys because this will only make things worse.

  • Adjust the room temperature so that it will be warmer.
