Crystals in urine are usually detected in a urine analysis. The only visible sign you may notice if you have urinary crystals is cloudy urine; however, some types of crystals in urine are not visible at all without a microscope. Your kidneys are needed to filter out waste products from the body and excess fluid, and these end up in urine. The kidneys are also responsible for regulating salt, urinary acid content, and other minerals in the urine. If you have kidney problems or your urine is too concentrated, urinalysis may show up that there are too many crystal substances in your pee.

It can be difficult to identify bed bug bites because the red itchy bumps caused by bed bug bites look like flea bites or mosquito bites. Bed bugs usually come out at night and feed on the blood of humans. The tiny nasty pests can leave a cluster of bite marks on your face, arms, stomach, and legs. Some people only have a mild reaction to the bed bug bites and may only have a few small red dots. However, others have more severe reactions and are plagued by large red bite marks and an irresistible urge to scratch them.

Skin peeling between toes is a condition affecting many people and is often caused by a fungal infection or dry skin. Because your toes and feet spend most of the day in footwear, the dark moist conditions can cause skin between your toes to peel and flake off. Germs can quickly multiply and cause infections making the skin between your toes itchy, red, cracked, and prone to peeling. You may find that the peeling skin starts between your two smallest toes and then spreads to areas in between your other toes.

Left eye twitching caused by a muscle spasm can be a disturbing condition that makes you self-conscious. Having a chronic eyelid tic or twitch in your left eye has many causes. Thankfully, it’s very rare that twitching in your left eye or right eye means that you have a serious medical condition. A lack of sleep, stress, eye strain, too much caffeine, or dry eyes are just some of the simple conditions that can cause left eye muscle spasms.

Pulled muscles in the chest can cause mild to excruciating pain in your upper body. You have two large muscles on either side of your chest – the pectoralis major and pectoralis minor, which are sometimes referred to as your “pecs.” A pulled chest muscle can cause a sharp severe pain that radiates to your shoulder or arm. Because of this, the symptoms of pulled, strained, or torn muscles in the chest can be similar to a heart attack. Of course, it’s important to have any pains in your chest checked out especially if there is no discernible cause and the chest discomfort is accompanied by other symptoms.

Noticing black spots on your tongue or other types of dark patches in your mouth can cause you to worry. Sometimes the cluster of black spots at the back of your tongue can resemble black hairs and is called a black hairy tongue. Other times the black or dark tongue spot could be due to a tongue injury that causes a blood blister to appear. Hyperpigmentation of the tongue is a side effect of some medications and can cause dark patches on your tongue. Sometimes, smoking or other conditions can cause staining in your mouth and cause your tongue, cheek, or other parts of the oral cavity to have a dark discoloration.

Bed bugs can leave a nasty cluster of bites on your skin that can last for a few days. For some people, however, bed bug bites can cause allergic reaction and symptoms that last much longer. Bed bug bites can cause a red bump to appear on the skin that becomes very itchy and irritating. Although scratching the itchy bump may give some temporary relief, it can cause the bed bug bites to last even longer.
