Athletes are the ones who will often have sore feet as well as other injuries to the feet as a result of high-intensity activities that they do. If you do partake in sports activities, be sure that you do not over-exert and put unnecessary demands on your feet. The foot is made up of numerous small bones which might break, crack, or splinter under the stress of too much demand. The symptoms of a hernia and groin pull are very similar so it is easy to confuse one with the other. Understanding the causes and symptoms of each may help you to differentiate between the two. A muscle tear in the back occurs when a back muscle is overstretched or torn. The muscle cells that are grouped together to form a muscle, muscle fibers, are damaged. Muscle tears are also termed "back strain" or "pulled back muscles." Muscle tears result from misused or overused muscles or even a fall or twist. Rehabilitation of a torn back muscle requires a good physician, time and a lot of patience. Doctors generally suggest bed rest to repair and rehabilitate a torn muscle. There are other things that an individual can do as well. All warts are caused by the human papilloma virus or HPV. There are a number of different strains of this virus, and each can cause different types of warts on different parts of the body. Wikipedia tells us that virus types 1, 2, 4 or 63 cause the foot wart, which is also known as a verruca or plantar wart. Unfortunately when walking around we cannot avoid applying pressure to these warts on toes or warts on foot, so they can often become very painful if not treated and they can make walking very uncomfortable. Believe it or not, pizza can be good for the environment. Using a pizza box, you can harness the power of the sun to make a cheap, simple and effective hot dog cooker. Solar energy is clean and renewable, unlike the firewood or fossil fuels you would traditionally use to cook hot dogs, so you're doing the environment a favor. The hot dog cooker is useful for camping trips, science projects and pure entertainment. Lead-acid batteries utilize an electrochemical reaction to produce and store electrical energy. The battery plates within a lead-acid battery react to the acidic electrolyte, and electrons move from one part of the battery to the other. And she explained, very sincerely, in her sweet country drawl; "If I don't give them the money, they will go out and find the money some other way. They will steal it, or hurt someone to get it. They will end up in jail. I will be at fault, because none of that would have happened if I had only given them the money to begin with. If I give them what they want, I can stop other people from getting hurt. I can stop them from going to jail." Texans lineman Duane Brown will have his 78-game consecutive starts streak snapped due to a sprained toe. (Frederick Breedon/Getty Images) A hammer toe is a toe that is contracted at the PIP joint (middle joint in the toe), potentially leading to severe pressure and pain. Ligaments and tendons that have tightened cause the toe's joints to curl downwards. Hammer toes may occur in any toe except the big toe. There is often discomfort at the top part of the toe due to rubbing against the shoe. Hammer toes are classified based on the mobility of the toe joints. There are two types - flexible and rigid. In a flexible hammer toe, the joint has the ability to move. This type of hammer toe can be straightened manually. Cause. If the hooves are not properly trimmed on a regular basis, the horse is more susceptible to suffering from navicular due to abnormal growth of the hoof. The hoof grows and wears in accordance with the footing that the horse is kept on. The bone may become immobile and cause poor circulation in the hoof. In extreme conditions, the coffin bone will slowly sink to the floor of the hoof and may pierce the bottom of hoof. The condition usually occurs only in the front feet and generally affects both feet. Hammertoes are most commonly found on the second (next to the big toe) and fifth (or small) toes. Because of this abnormal toe position, the joint of the toe becomes prominent on top of the buckled toe. The tendons and ligaments then begin to contract and accelerate the problem. Skin irritation (inflamed skin areas) or even corns – (an accumulation of hard dead skin cells) may form on top of these prominent, contracted joints where shoes are likely to rub. This usually will lead to pain and inability to wear some types of shoes comfortably, especially if the pressure or corn is on the small toe.
