White spots on the skin could also be calluses, especially if you've been wearing shoes that pinch your feet. These aren't usually a serious problem, and can be treated in the same way as patches of hard skin. If the patches feel lumpy or painful it would be best to visit your doctor (GP).
Piezogenic pedal papules are small, yellow to white bumps that occur on the bottom and sides of the foot when weight bearing, and they disappear when non-weightbearing. They can also present when pressure is applied to the foot. They are generally considered as normal variants and are not usually painful.
Summary. There are many reasons why dark spots on bottom of feet appear. Two of the most common causes are stasis dermatitis and melanomas of the foot. While stasis dermatitis mostly arises from age and lack of activity, melanomas come from multiple sources and can happen to anyone of any age.
There are a number of possible causes of a bump on the bottom of the foot which may be: On The Skin: e.g. calluses, corns, warts, eczema. Under The Skin: e.g. fibroma, bursitis, cysts, tumors. At The Bone: e.g. bone spur, fracture, gout.
Aside from looking like a changing mole, a melanoma on the foot can appear as a: Brown or black vertical line under a toenail. Pinkish-red spot or growth. New spot or growth where you injured your foot.
If you have yellow or white bumps that look like pimples on your feet, this may be caused by whiteheads, skin abscess, or cysts.
Another effective way to get rid of foot fungus is to use an antifungal foot soak. This can be done by adding a few drops of tea tree oil, or a few tablespoons of apple cider vinegar, to a basin of warm water. Soak your feet in the solution for 20-30 minutes, and then dry your feet thoroughly.
Athlete's foot (tinea pedis) is particularly common between the little toe and the toe next to it. The fungus can cause the skin to redden and crack. The affected areas are flaky and sometimes itchy. The skin can also turn white and thicken, and is then often slightly swollen.
A hard corn is a compact patch of hard skin with a dense core, on top of a toe or the outside of the little toe. A soft corn is a reddened, tender area of skin. It has a thin, smooth center and is found between toes. A seed corn is a plug-like circle of dead skin, often painful, on the heel or ball of the foot.
Corns and calluses are thick, hardened layers of skin that develop when the skin tries to protect itself against friction or pressure. They often form on feet and toes or hands and fingers.
White mold is a type of fungus that can cause health issues for individuals, with symptoms ranging from skin irritation, coughing fits, and limited breathing. The severity of the symptoms depends on the amount of mold spores people are exposed to and their own sensitivity levels.
Tinea versicolor is a fungal skin rash. It's caused by too much growth of a normal yeast on the skin. The most common symptom is patches on the skin that may look white, pink, or light brown.
Your skin may appear irritated (red, purple, gray or white), scaly or flaky.
Maybe it doesn't hurt, and the yellow, thick nails don't bother you. But nail fungus doesn't go away by itself. And if you don't treat it, there's a chance it could get worse.
Vitiligo is a long-term condition where pale white patches develop on the skin. It's caused by the lack of melanin, which is the pigment in skin. Vitiligo can affect any area of skin, but it commonly happens on the face, neck and hands, and in skin creases.
Vitiligo is a chronic (long-lasting) autoimmune disorder that causes patches of skin to lose pigment or color. This happens when melanocytes – skin cells that make pigment – are attacked and destroyed, causing the skin to turn a milky-white color.
Melanoma can be tricky
Amelanotic melanomas are missing the dark pigment melanin that gives most moles their color. Amelanotic melanomas may be pinkish, reddish, white, the color of your skin or even clear and colorless, making them difficult to recognize.
Stage I melanoma is no more than 1.0 millimeter thick (about the size of a sharpened pencil point), with or without an ulceration (broken skin). There is no evidence that Stage I melanoma has spread to the lymph tissues, lymph nodes, or body organs.
Purulent drainage is a sign of infection. It's a white, yellow, or brown fluid and might be slightly thick in texture. It's made up of white blood cells trying to fight the infection, plus the residue from any bacteria pushed out of the wound.
The only way to know whether you have a bacterial, viral, or fungal infection is to be tested for them by a qualified medical professional. Many common ailments such as diarrhea or pneumonia can be caused by either bacterial or viral infections.
