Dehydration occurs when someone loses enough water to prevent the body from functioning properly. Severe dehydration can cause high potassium levels (hyperkalemia), which are dangerous if immediate treatment is not given. The medical term for a toothache is odontalgia. A person is considered to have a toothache whenever there is pain in or around a tooth. There are several reasons a person may experience a toothache. Cavities, gum disease, and an infection can all cause tooth pain. If you are suffering from a toothache resulting from an infection, there are some home remedies you can try to reduce the infection and the pain. Flexible flat feet generally do not require any treatment at all. Special shoes, shoe inserts and exercises do not lead to flat foot correction. For children younger than eight, physicians tend to recommend observation only. Doctors may recommend orthotics (shoe inserts) for middle- or high school-aged children with pain which seems to be due to flat feet. Orthotics provide support to the arch of the foot and decrease the amount of pronation (ankles rolling inward). Pes planus (also called flat foot ) is a deformity of the foot where the longitudinal arch of the foot is abnormally flattened. Pathology Hubby has the flexible type of flat foot that began in his childhood and is continuing in adulthood. Flexible flat foot means that while the foot is flat when standing in a full weight bearing position, a bit of an arch is noticable when not standing. However, if hubby is too tired due to standing the whole day at work in his office laboratory, then the arch is totally absent even when he is not standing. The amount and degree of this motion (or lack of) is a major factor in determining if a particular foot type should be evaluated, and possibly treated, by a foot specialist. Sinus tarsi syndrome is often a clinical finding observed in people affected by trauma to the foot or poor foot biomechanics. The best way to lower the incidence of this condition is to seek medical assistance for proper treatment of ankle sprains or other injuries. Correction or treatment of structural foot abnormalities will go a long way in lowering the risk of this foot problem. This group has devices that offer relief to minor pains and foot injuries. They are usually used to correct problems in children. The devices include night bars and splints. They offer support and promote adjustments for minor abnormalities. Cervical discectomy and cervical fusion are two surgical techniques designed to address pain and instability in the bones (vertebrae) of the neck. Surgeons frequently use the two procedures in combination. Diseases of the spine are more common than you might think. There are several forms of bone diseases of the spine that range from mild to life threatening. These diseases can occur at any time in your life from inherited factors, age and environment. Spine diseases can also occur spontaneously without any particular causes. These factors make it vitally important to be aware of different spine diseases and how they can affect your health. Taping and self-massage with the use of a tennis ball can also be helpful. Icing will help reduce inflammation and pain and the use of a night splint may be indicated. During sleep our feet typically assume a pointed (plantar flexed) posture, which is a shortened position for the plantar fascia. When the alarm goes off and we get out of bed and flex the foot in the other direction (dorsiflexion), we put an immediate stretch on the plantar fascia. Night splints help maintain the dorsiflexed posture so that the plantar fascia isn't as stressed when you get out of bed. High arches tend to be the more prevalent of midfoot dysfunctions. They occur due to significant shortening of the soft tissues of the medial longitudinal arch. Often, this is a trained response to the types of shoes we wear. For years, shoe manufacturers have increased the amount of arch support, especially in running shoes. However, more is not always better. The increase in support leads to weakening of the muscles as they no longer have to work to support the arch. The other soft tissues, such as ligaments and fascia, will shorten because of the prolonged posturing due to the arch support. The flat foot, also called pes planus , is pronated with a flattened longitudinal arch.The hindfoot may be in valgus. Occasionally, there is an associated accessory navicular bone. In this congenital deformity, the ossification center of the navicular tuberosity fails to fuse to the main bone and remains a bony prominence on the medial side of the foot. These are often locally symptomatic and require protection or surgical excision. Usually the original onset of a flat foot problem creates restrictions in the foot functional activity and with the introduction of different artificial support systems, such as foot orthodics, this problem is temporarily moved aside, but not solved.
