Small blackish warts on the hand and foot are usually caused by a common viral infection called Human papillomavirus infection, and they are generally harmless but can cause irritation. Many warts go away on their own, but if you want treatment, over-the-counter options like salicylic acid solutions or wart-removal patches can help gradually remove them when used regularly, while protecting the surrounding skin. It is important not to pick or cut the warts, as this can spread the infection. If they are painful, increasing in size, spreading, or not improving after a few weeks, a doctor can treat them more effectively with methods like freezing (cryotherapy), cautery, or minor procedures. Keeping the area clean and dry and avoiding sharing personal items can help prevent the spread.

Painful, dot-like spots on the foot for months are often due to warts or thickened skin from pressure that irritates the area while walking. Keep the area clean and dry, and try using soft, cushioned footwear to reduce pressure on the spot, making walking less painful. Avoid picking or cutting the spots, as this can worsen pain and spread the problem. You can gently soak your foot in warm water to soften the skin and ease discomfort. Limit long periods of standing or walking until it improves. If the pain is increasing or the spots are spreading, consult a doctor for proper treatment and relief.
