My daughter is limping from this hard rough spot with black dots on her sole. She has a dance recital tomorrow and is crying in pain. Need a fast fix!

The description of a hard, rough spot with black dots on the sole is commonly associated with a plantar wart. These warts are caused by the human papillomavirus (HPV) and typically develop on the weight-bearing areas of the feet, such as the heels or balls of the feet. The black dots are small, clotted blood vessels and are a distinguishing feature of plantar warts.

Plantar warts can vary in size, typically ranging from a few millimeters to a centimeter in diameter. They can be painful due to their location on the sole, as pressure from standing or walking presses them into the foot. The rough texture is due to the thickened skin over the wart, which can sometimes resemble a callus.

To differentiate a plantar wart from other common foot issues like splinters, blisters, or calluses, closely examine the affected area. Plantar warts are generally round and have a rough surface with tiny black dots (clotted blood vessels) within them. Unlike a splinter, they are not associated with a specific point of entry or foreign object under the skin.
