What is it? Jogger’s nipple (or runner's nipple) is common in runners. It happens when nipples are irritated by rubbing against clothing which moves up and down as you run. Symptoms Runner's nipple can be very painful and affect one or both nipples. Common symptoms of jogger’s nipple include: Irritation Soreness Redness of the skin Dryness If the nipple is irritated for a long period it may crack and bleed. Causes Runner's nipple is common in women who run without a bra and men who wear shirts that are made of coarse material such as cotton. It is also more likely to occur in colder months when the nipple is hard or more prominent. Treatments A short rest from running will prevent further irritation and help your nipple heal. You can use an antiseptic cream on your nipple to treat the irritation and prevent infection. Vasaline will also help to prevent further irritation. Do Apply an anti-chafing balm or petroleum jelly, such as Vasaline, to your nipples prior to exercise. Apply a waterproof adhesive bandage, or surgical tape over each nipple before exercise to act as a barrier between skin and cloth. If you are a woman, wear a soft fibre and seamless bra. If you are a man wear tops made from soft material. Wear a sports bra, shimmel, compression vest, or some variety of chest binding clothing. Don’t Wear tops made of coarse material. Use a large, loose-fitting T-shirt during exercise.
