Three out of four people will experience a common foot problem in their lifetime. These conditions can be painful and embarrassing. However, while walking a lot or wearing improper shoes can be the main culprits of sore feet, there are a number of other conditions that your painful peds could be squealing about.
Heel Pain:
The most common cause of heel pain is plantar fasciitis. Arthritis, excessive exercise, and poorly fitting shoes also can cause heel pain, as can tendonitis. Less common causes include a bone spur on the bottom of the heel, a bone infection, tumor, or fracture.
Bone infection:
This is a painful infection that can cause inflammation of the bone marrow from infectious bacteria.It primarily affects the long bones in the legs and arms. The skin around the affected area can become swollen, and there could even be symptoms of fever and chills.
Gout:
Gout pain is caused by uric acid crystals that are deposited in joints and other areas causing redness, swelling, pain, and stiffness.One of those areas happens to be your big toe.While this is very painful, a gout attack can have triggering factors such as stress and alcohol.
Swollen feet:
This is usually a temporary nuisance caused by standing too long or a long flight.In contrast, feet that stay swollen can be a sign of a serious medical condition. The cause may be poor circulation, a problem with the lymphatic system, or a blood clot. A kidney disorder or underactive thyroid can also cause swelling.
Burning feet: 
A burning sensation in the feet is common among diabetics with peripheral nerve damage. It can also be caused by a vitamin B deficiency, athlete’s foot, chronic kidney disease, poor circulation in the legs and feet (peripheral arterial disease), or hypothyroidism.
Athlete’s foot:
Itchy, scaly skin may be athlete’s foot, a common fungal infection. If the skin on itchy feet is thick and pimple-like, it may be psoriasis, an over-reaction of the immune system. Medicated creams can relieve the symptoms.
Spasm foot:
A sudden, sharp pain in the foot is the hallmark of a muscle spasm or cramp, which can last many minutes. Overwork and muscle fatigue are common causes. Other causes include poor circulation, dehydration, or imbalances in potassium, magnesium, calcium, or vitamin D levels in the body.
Ingrown toenails:
Ingrown toenails are generally caused by poor nail-cutting technique, abnormal nail shape or poorly fitted footwear resulting in pain, redness, swelling or sometimes infection in the nail.
Dragging feet:
Sometimes the first sign of a problem is a change in the way you walk — a wider gait or slight foot dragging. The cause may be the slow loss of normal sensation in your feet, brought on by peripheral nerve damage. Nerve damage also can be due to infection, vitamin deficiency, and alcoholism. Other possible causes for foot dragging include problems with the brain, spinal cord, or muscles.
Cold feet:
If your toes are always cold, one reason could be poor blood flow sometimes linked to smoking, high blood pressure, or heart disease. The nerve damage of uncontrolled diabetes can also make your feet feel cold. Other possible causes include hypothyroidism and anemia.
Red, white or blue toes:
Raynaud’s disease can cause toes to turn white, then bluish, and then ridden again and return to their natural tone. The cause is a sudden narrowing of the arteries, called vasospasms. Other diseases associated are chilblains due to poor circulation in the arteries due to cold.
