Summer is right around the corner and that means hibernating toes are about to experience a breath of fresh air. Here, Dr. William Knudson touches base on foot care with advice on how to feel confident when your feet are finally free.
Practice with a Pumice
A pumice stone is a foot’s best friend all year, says Dr. William Knudson. But it is especially important in the spring and summer months when feet are exposed. Soak feet in warm water, infused with black tea or Epsom salt, for about 15 minutes. Pat dry then carefully smooth away calloused and cracked skin.
Dr. William Knudson says running is a fantastic way to stay healthy. It burns plenty of calories, improves cardiovascular function, and can help tone and tighten out-of-shape leg muscles. However, running is also a high-impact activity and can lead to serious foot, ankle, or leg injuries. Here, Dr. Knudson addresses common running injuries.
Q: What is Achilles tendinitis?
Dr. William Knudson: Achilles tendinitis refers to an injury of the Achilles tendon, which is the tissue that connects the heel bone and calf muscle. It requires a medical diagnosis and often resolves within weeks. It is a common injury in adults and teenagers who play sports that involve running, especially for those who partake in physical activity only occasionally. Key symptoms are tenderness and pain in the heel.
Q: How is Achilles tendinitis different from sesamoiditis?
Dr. William Knudson: Sesamoiditis is an overuse injury that affects the forefoot. It results from repeated trauma to the sesamoid bones which are located behind the big toe. The sesamoid bones provide leverage and act as a weight-bearing surface. In addition to running, sesamoid bone injuries are common in those who play football, tennis, basketball, and golf.
Dr. William Knudson describes platelets as the blue collar workers of the blood. They are the cells that do the hard work of repairing soft tissue upon injury. Now, advancements in pain management mean doctors can harness the power of the platelet to promote growth and heal injuries using the body’s own defense system.
Plasma Rich Platelet therapy, or PRP, is an advanced treatment method that involves extracting platelets from the blood and injecting them directly into an injured area, Dr. William Knudson explains. The procedure usually lasts under three hours per visit, including preparation, injection, and recovery time. Performed in-office without the use of anesthesia, most patients report returning to regular activities the same day. PRP therapy is spread out over the course of six months. During this time, the attending physician will monitor pain levels and check for new, healthy growth in the damaged area.
Lyme disease is the fastest infectious disease on the planet. The Centers for Disease Control and Prevention estimate that every year 300,000 Americans are infected with the disease. Below, Dr. William Knudson explains Lyme disease symptoms, treatment and prevention.
Q: Where does Lyme disease occur?
Dr. William Knudson: Although Lyme disease has been found in many states, more than 95 percent of cases come from the Northeast to upper Midwest, ranging from Maine to Virginia.
Q: How does a person get Lyme disease?
Dr. William Knudson: You can get Lyme disease from a black-legged deer tick. The
tick jumps on the person and inserts its pincers into the skin. It then stays attached and feeds off the blood. In return, the tick injects the bacteria Borrelia Burgdorferi into the person.
