One of the primary symptoms that is so common with a malarial infection is a high fever, at least 102°F (38.9°C). It's also one of the first symptoms to appear as early as seven days (although usually between 10 – 15 days) after getting bitten by an infected mosquito. Often the fever comes and goes randomly. This is thought to be related to the malaria parasites transiently spreading into blood from the liver.  There are at least five types of Plasmodium parasites that infect people, although P. falciparum (mainly in Africa) and P. vivax (mainly in Latin America and Asia) are the most common and deadly. The fever and other initial symptoms may be mild and mimic less serious viral infections, such as the common cold and influenza. Usually symptoms don't appear for about two weeks after being bitten. The other primary symptom of malaria is severe shaking chills with intermittent periods of sweating. Again, shaking chills are typical of many other types of infections, but they are usually more pronounced and severe with malaria. They can cause teeth to chatter and even prevent sleep. When they're severe, the shaking can be mistaken for seizures. The chills from malaria are usually not remedied by blanket cover or by wearing warmer clothes.  Although the primary symptoms of malaria typically begin within a few weeks of being bitten by an infected mosquito, some types of malarial parasites can lie dormant in the body for up to a year or more.  Malarial symptoms are caused by the bites from female Anopheles mosquitoes, which inject the parasite into the host's bloodstream. The parasites then migrate to the liver where they lay dormant for a week or two before causing symptoms. Secondary and less specific symptoms of malaria are moderate-to-severe headaches, often combined with mild muscle aches. These secondary symptoms often occur a short while after the above-mentioned primary symptoms as the parasite needs a little more time to proliferate in the liver and spread around the body in the bloodstream. Headaches and muscle aches are also very common with most other infections, as well as from the bites of other insects and spiders.  The bites from female Anopheles mosquitoes are not very noticeable (a small, red, itchy bump), unlike the bites of some other insects and spiders that can cause similar symptoms. The initial headaches of malaria are typically dull in nature (like a tension headache), but as the parasites start to infect and destroy red blood cells, they can become pounding in nature (more like a migraine). The achy pain is usually most noticeable in the leg and back muscles because they are larger, more active and get more of the infected blood. Other non-specific secondary symptoms of malaria are vomiting and diarrhea, multiple times per day. They often occur in combination with each other, which mimics the initial symptoms of food poisoning and other bacterial infections. The main difference is that the vomiting/diarrhea caused by food poisoning fades away within a few days, whereas it can remain for a few weeks with malaria (depending on treatment).  Unlike the explosive and bloody diarrhea of some bacterial infections, particularly Shigella, there's usually no blood or severe cramping with malaria. Once the primary and secondary symptoms become noticeable, the malaria-causing parasites can be seen under a microscope from a drop of infected blood — especially if the specimen is stained with Giemsa stain. If the advancing primary and secondary symptoms don't prompt the infected person to seek medical attention and get treatment (which may not be possible in the developing world), then symptoms begin to appear that signify serious injury / damage to the body. When these advanced symptoms of malaria appear, the risk of health complications and death significantly increase.  Confusion, multiple convulsions, coma and neurological impairment indicate brain swelling and injury. Severe anemia, abnormal bleeding, deep labored breathing and respiratory distress indicate advanced blood infection and lung involvement. Jaundice (yellowish skin and eyes) is evidence of liver damage and dysfunction. Kidney failure Liver failure Shock (very low blood pressure) Enlarged spleen

Article: If you are having pain across these areas, it is most likely caused by an injury to the back muscles, not the kidneys. These are common areas of back pain and it is more common for back pain to spread across this whole region than for kidney pain to spread in this way.  An injury to the back muscles can impact the function and pain levels in a variety of muscles down the backside of the body, including the gluteus muscles. If you are having widespread pain, weakness, or numbness, especially down into your legs, it is important to get medical care immediately. Kidney pain is most often located on the side or the back in the area called the flank. This is the area at the back of the body where the kidneys are located. Pain in other areas of the back, such as the upper back, is not caused by the kidneys. If the pain in your lower back is accompanied by pain in your abdomen, then it is more likely that your pain is related to your kidneys. Back pain tends to remain on the back side of the body. Enlarged or infected kidneys can cause inflammation towards the front of the body in addition to the back. If you only have abdominal pain with no back pain, that is not likely to be related to the kidneys. In many cases, kidney pain is constant. It may decrease or increase a bit throughout the day, but it never goes away completely. On the other hand, back pain will often go away completely and then come back at a later time.  Most causes of kidney pain, including urinary tract infections and kidney stones, will not stop hurting on their own without treatment. The back muscles, on the other hand, can heal themselves and the pain can go away. Some kidney stones can pass through your body on their own without treatment. However, it is still important to get the cause of your kidney pain evaluated by a doctor. If you are having pain on just one side of your flank, then it is likely that it is caused by your kidney. The kidneys are located right along the flank and a kidney stone may only cause pain in one of your kidneys.
