Causes, Symptoms, and Treatment of Poor Blood Circulation in the Feet
Poor blood circulation in the feet and legs is often caused by peripheral artery disease (PAD), which is usually the result of a build up of plaque in the arteries. Plaque build up, or atherosclerosis, can be the result of excess calcium and cholesterol in the bloodstream, which restricts how much blood can flow through arteries. Reduced blood flow to a certain area of the body severely limits the amount of oxygen and nutrients that part of the body receives, causing degeneration in the muscles and other tissues. Sometimes, poor blood circulation in the feet and legs can be caused by other conditions, such as damage to or inflammation of blood vessels, known as vasculitis.
The lack of oxygen and nutrients caused by poor blood circulation can restrict muscle growth and development, as well as cause muscle pain and cramps, weakness, and stiffness. Other common symptoms include numbness in the legs and feet, skin discoloration in the affected limbs, slower nail and hair growth, and erectile dysfunction in men. In more severe cases of PAD, pain can be present even when a person isn't exercising, and may range from mildly uncomfortable to completely debilitating.
Poor blood circulation in the feet and legs is more common in those who are overweight or obese, have diabetes, high blood pressure, high cholesterol, who smoke, or who have a family history of PAD or related conditions (heart attack, stroke, etc.). Diabetes and smoking place a person at greatest risk for developing poor blood circulation, although advanced age (over 50) can also increase risk.
If you are experiencing poor blood circulation in the feet and legs caused by PAD, it is important to make changes to your lifestyle in order to reduce your risk of experiencing a heart attack or stroke caused by this condition. If you smoke, quit completely -- this will increase the amount of oxygen in your bloodstream. Exercising and reducing the saturated fats in your diet (which come from fatty meats, fried foods, whole milk, etc.) can make a difference in improving blood circulation in feet. It is also important to avoid developing influenza and to carefully control your blood sugar if you have diabetes.
Your doctor may recommend combining lifestyle changes with a prescription medication regimen to improve blood circulation. The most commonly-used medications for PAD are called statins and work by blocking the amount of enzymes in your body that produce cholesterol. They are known by the brand names Zocor, Lipitor, Crestor, and others.
Flip-flops and Feet
Flip-flops are some of the most comfortable and convenient kinds of shoes there are. They let you freely move your toes, aren't constrictive, and allow your feet to breathe. They can also be worn with almost any attire, and match most clothing styles. Unfortunately, wearing flip-flops can also be very dangerous. These sorts of shoes can harm your feet in more ways than you may think.
Although they are comfortable, constant flip-flop use can lead to problems with the ankles, hips, and lower back if worn on a long-term basis. This is because people walk much differently in flip-flops than they do in other shoes like sneakers. Their natural gait is being forced to change, throwing the body off and causing stress to different parts of the body. Flip-flops can also lead to problems in the arches of your feet, and pain in the balls of your feet. There is little to no support provided by flip-flops, so some parts of the foot undergo much more stress than normal.
Flip-flops can cause more obvious short term problems as well, like ankle sprains and frequent blisters. Because these shoes are relatively weak and can easily bend while walking, wearers are far more likely to trip and hurt their ankles. Flip-flops can also cause bad blisters, because their straps are constantly rubbing up against the foot. Additionally, someone wearing flip-flops is more prone to infections, due to the openness of the shoe. It very easy to scrape and cut your foot when wearing flip-flops because they offer little protection for the foot. If left untreated and uncovered, these same cuts can get dirtied and infected as flip-flops wearers walk around.
In order to avoid this, make sure to get a pair of flip-flops that will keep your feet as safe as possible. When looking to purchase flip-flops, you should check that the actual sole is sturdy and firm. The flip-flops are too floppy if the sole droops and wiggles a great deal when lifted off the floor. These will offer very little support, and may lead to other problems like tripping.
If you only purchase flip-flops made of high quality, sturdy materials, you won't have to worry about this. Although they will cost a little more, flip-flops made of these materials will last longer, and will protect your feet more so than a cheap pair of flip-flops. Also, make sure to buy from a reliable brand name. You can often find relatively cheap shoes from these companies, and once you have bought them you know they will last.
You can still wear your favorite flip-flops, just avoid wearing them every day of the week, or for extended periods of time. It is also recommended that you replace flip-flops every three or four months, in order to be sure that they provide maximum protection to your feet.
What to Know About a Broken Toe
Although most people try to avoid foot trauma such as banging, stubbing, or dropping heavy objects on their feet, the unfortunate fact is that it is a common occurrence. Given the fact that toes are positioned in front of the feet, they typically sustain the brunt of such trauma. When trauma occurs to a toe, the result can be a painful break (fracture). Another type of trauma that can break a toe is repeated activity that places stress on the toe for prolonged periods of time.
Broken toes can be categorized as either minor or severe fractures. Symptoms of minor toe fractures include throbbing pain, swelling, bruising on the skin and toenail, and the inability to move the toe with ease. Severe toe fractures require medical attention and are indicated when the broken toe appears crooked or disfigured, when there is tingling or numbness in the toe, when the injured person experiences fever or chills throughout their body, and when there is an open, bleeding wound present on the toe.
Generally, a minor toe break will heal without long-term complications, but it is important to discontinue activities that put pressure on the toe. It is best to stay off of the injured toe with the affected foot elevated on pillows. Swelling can be alleviated by placing an ice pack on the broken toe for 15 minutes every two hours during the first two days after the fracture. The broken toe should be immobilized by placing a small cotton ball between the injured toe and the toe beside it, then taping the two toes together with medical tape.
Severe toe fractures may be treated with a splint, cast, and in some cases, minor surgery; especially when the big toe has been broken. Due to its position and the pressure it endures with daily activity, future complications can occur if the big toe is not properly treated. Pain associated with minor toe fractures can be managed with over-the-counter pain medications, and prescription pain killers may be necessary for severe toe fractures.
The healing time for a broken toe is approximately four to six weeks. In severe cases where the toe becomes infected or requires surgery, healing time can take up to eight weeks or more. While complications associated with a broken toe are immediately apparent, it is important to note that there are rare cases when additional complications, such as osteoarthritis, can develop over time.
Choosing the Right Running Shoe for Your Foot Type
While running seems like a simple activity, it is actually a complicated movement that puts a lot of stress on the joints, bones and ligaments of the body. Consequently, choosing the right shoe is an important step in increasing performance and decreasing injury risk. You should select running shoes based on your foot type. While other considerations are important, such as trail versus road shoes, your foot type dictates the amount of cushioning, stability and motion control you need. The best way to determine your foot type is to visit a local specialty running shop. Professionals there can measure your arch type, stride and gait and summarize your shoe needs for future reference.
Running shoe design is based on the idea of pronation. Pronation is the natural rolling of your ankle from outside to inside during foot strike. In other words, proper running mechanics involve striking the ground on the outside of your heel and rolling toward your big toe before pushing off again. Pronation is a good thing: it helps your lower extremities absorb shock and store energy. Neutral runners who pronate correctly do not depend on their shoes to correct their form. Neutral runners can select from a large variety of shoes, even minimal or barefoot models. However, runners with problematic foot arches or incorrect form may pronate too much or too little and require specific qualities from their running shoes.
Overpronators run with excessive ankle rolling. Even when standing, severe overpronators exhibit ankles that angle inward. They also tend to have flat feet or bowed legs. Overpronation can cause a plethora of injuries, especially in the knees, ankles and Achilles tendons. If you overpronate, you should select a shoe with extra stability and motion-control. Motion-control shoes are firm and straight; they do not curve at the tip. The lack of flexibility along the midsole prevents the foot from rolling too far inward during your foot strike.
Underpronation, also called supination, is less common than overpronation. Unlike overpronators, underpronators have inflexible feet and high arches. When they land, their feet are unable to roll inward. While this places less rotational stress on the ankles and knees, it prevents any kind of shock absorptions. This additional force can result in fractures, ligament tears and muscle strains as the legs compensate for the impact. Underpronators require shoes with increased cushioning and flexibility. If you underpronate, stability or motion-control shoes may compound the problem by further preventing pronation.
