Headaches are a source of pain and misery and having a headache behind or above your right eye can be especially distressing. Experiencing pain on the right side of your forehead can feel like extreme pressure that creates a dull ache behind your eye. Sometimes the headache above your right eye can become more intense and feel like stabbing or shooting pains that radiate from the right side of your forehead and cause pain at the back of your head.

Rhomboid muscle pain is felt between your shoulder blade and spine in your upper back and is caused by stretching, straining, or tearing your rhomboids. Your rhomboid muscle comprises of 2 parts – the minor rhomboid muscle and the major rhomboid muscle. Sudden arm movements, muscle injury, or repetitive strain injuries can stretch or tear the rhomboid muscle, causing pain and stiffness just beneath the neck between your shoulder blades.

MCV blood test is part of RBC indices (red blood cell indices) and checks the mean corpuscular volume of your blood cells to help doctors check the health of your blood. The MCV blood test shows the average size of your red blood cells. Red blood cells (RBCs) play an important function in transporting oxygen and nutrients to tissue. Red blood cells that are too large or too small can be an indicator of an underlying medical condition. That is why doctors will check the average size of your red blood cells.

Implantation cramping happens when a fertilized egg attaches itself to the wall of the uterus. Cramps that happen around the time of implantation are one of the first signs of pregnancy along with light spotting (also called implantation bleeding or implantation spotting). Because implantation cramping can happen just before your period, many women mistake the pelvic pain for the start of their period.

Having an itchy belly button can be an embarrassing problem that can cause discomfort in your daily activities. Belly buttons often start to itch because they can become easily infected. An infection in or around your navel can cause patches of red itchy skin that may ooze discharge and crust over as it heals.

Small deposits of calcium salts can happen anywhere on the body, but calcium deposits on the face can be especially distressing. Facial calcium deposits can look like small white bumps on the cheeks, forehead, around the eyes, and near the ears. These groups of whitish pimple-like nodules, known as calcinosis cutis, occur just under the skin and can be caused by acne on the face, trauma to the facial skin, an overactive thyroid gland, or other underlying medical conditions.

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.
