By the fifth or sixth day, a pustule about one centimeter in diameter will develop on the site of the initial wound. The affected skin might be reddened, itchy, and scaly. As the inflammation continues, part of the skin will progress from a rash that’s itchy and scaly to dry and peeling.

It might be oval or round in shape. If you have jungle rot, your ulcer could be from half an inch to thirteen inches in diameter. Your ulcer’s size will depend on your overall health and nutrition. The healthier you are, the less serious your ulcer will be. The ulcer will grow quickly during the first three weeks, then slow in growth until it reaches its maximum size after about six weeks.

In severe cases, there is marked disability where one is unable to walk. This may occur when the infection spreads to the tendon, sheath and the bones. You can relieve pain with adequate bandaging. Use a non-adhesive dressing and change it daily. Wash the wound with clean water between dressings and pat dry.
