What Is Tennis Toe?

Tuesday, 14 September 2021 00:00

Tennis toe is a common sports injury where damage to the toe causes blood to collect beneath the toenail, giving the nail a black or red appearance. Other names for this condition include “subungual hematoma” and “runner’s toe,” as it is common among runners and other athletes who participate in activities that place immense pressure on the toes. In addition to nail discoloration, the affected toe may also throb, and the nail can thicken and become brittle. Although it can be painful, this condition is not indicative of a broken toe. Mild cases are treated by cleaning the affected nail with an antiseptic and covering it with a dressing to prevent infection, although it does take a few months for a new, healthy nail to grow out. Severe cases, characterized by significant bleeding, swelling or infection, may require a small hole to be drilled into the nail to drain the blood that has pooled beneath it. If you are suffering from tennis toe, please seek the care of a podiatrist. 

Ankle and foot injuries are common among athletes and in many sports. They can be caused by several problems and may be potentially serious. If you are feeling pain or think you were injured in a sporting event or when exercising, consult with Dr. Jennifer Woo from California. Our doctor will assess your condition and provide you with quality foot and ankle treatment.

Common Injuries

The most common injuries that occur in sporting activities include:

  • Achilles Tendonitis
  • Achilles Tendon Rupture
  • Ankle Sprains
  • Broken Foot
  • Plantar Fasciitis
  • Stress Fractures
  • Turf Toe


Symptoms vary depending upon the injury and in some cases, there may be no symptoms at all. However, in most cases, some form of symptom is experienced. Pain, aching, burning, bruising, tenderness, tightness or stiffness, sensation loss, difficulty moving, and swelling are the most common symptoms.


Just as symptoms vary depending upon the injury, so do treatment options. A common treatment method is known as the RICE method. This method involves rest, applying ice, compression and elevating the afflicted foot or ankle. If the injury appears to be more serious, surgery might be required, such as arthroscopic or reconstructive surgery. Lastly, rehabilitation or therapy might be needed to gain full functionality in the afflicted area. Any discomfort experienced by an athlete must be evaluated by a licensed, reputable medical professional.
