About the Symptom
It describes the warm sensation felt on the limb.
When to See a Doctor
Seek professional care if you experience any of the following symptoms
- Repeated fever above 38 ℃
- Fever
- Numbness / sensory disorder
- Recent weight loss
- Swelling of the affected area
Possible Causes
Generally, Hot hands and feet can be related to:
- Juvenile Idiopathic Arthritis (JIA)
Juvenile idiopathic arthritis (JIA) is a type of arthritis that occurs in children under 16 years old. It's a chronic condition characterized by joint pain and swelling that can last for months or years. It affects one or more joints for at least 6 weeks. JIA occurs when the body's immune system attacks its own tissues The cause of JIA is unknown.
- Diabetic Gangrene
With this condition, a wound (often in the feet) does not heal well due to diabetes. Diabetes weakens circulation and the immune system resulting in poor wound healing. Diabetes also decreases sensation in the extremities so people often do not have pain or notice the tissue until it is completed dead. The tissue becomes black and dry appearing as it completely dies off. This wound may also become a source of infection leading to spread of infection to other parts of the body.
- Gout / Pseudogout
Gout and pseudogout are diseases caused by inflammation and crystal accumulation in the joints. Gout results from uric acid crystals, while pseudogout stems from calcium pyrophosphate crystals. Both are marked by sudden, painful swelling in one or more joints. Gout attacks can be triggered by eating purine-rich foods like seafood, alcohol, and red meat, while pseudogout may be due to joint injury, surgery, or immune issues.
- Rheumatoid Arthritis (RA)
- Fabry Disease / Lysosomal Storage Disorder
- COVID-19
- Ear Infection
Related Serious Diseases
Sometimes, Hot hands and feet may be related to these serious diseases:
- Septic Arthritis
Septic arthritis is an infection of a joint space. This can be caused by a wound that penetrates the joint allowing bacteria to enter, complications following surgery, or by bacteria traveling from distant sites via the bloodstream into the joint.
- Cellulitis / Erysipelas
- Osteomyelitis
Doctor's Diagnostic Questions
Your doctor may ask these questions to check for this symptom:
- Do you have warm hands and feet?
- How often do you experience warm hands and feet?
- How long have you had hot hands and feet this time?

Q.
Why are my feet hot? Could this hot sensation in the soles be due to diabetes?
A.
Experiencing a hot sensation in the soles of your feet can be caused by various factors, and it may indeed be related to diabetes, particularly through a condition known as diabetic peripheral neuropathy. Understanding the potential causes is important for proper diagnosis and management.

Q.
Why do my hands and feet specifically become hot at night?
A.
At night, your body naturally sends extra blood to your hands and feet to help regulate your temperature for sleep, making these areas feel warmer. This process is a normal part of how your body prepares for rest.

Q.
Why do my legs feel hot even when the rest of my body is cool?
A.
Your legs may feel hot because your body sends extra blood flow to them, or because the nerves in your legs sense heat differently compared to the rest of your body.

Q.
How can I address hot hands and feet when there is no fever present?
A.
Hot hands and feet without a fever can be due to how your body controls blood flow and temperature, not an infection. Simple changes like better sleep, comfortable clothing, and a cool environment might help ease these sensations.

Q.
Is it normal for my baby to have hot hands and feet without a fever?
A.
It is common for a baby’s hands and feet to feel warm even when the baby does not have a fever. This is usually due to normal blood flow differences and the way a baby’s body manages temperature.

Q.

Q.
What could cause my legs to feel hot and heavy?
A.
Your legs feeling hot and heavy may be from changes in blood flow that cause extra blood to pool in your legs, making them feel warm and tired.

Q.
What could cause my legs to feel hot during the night?
A.
Hot legs at night can be linked to how your body regulates temperature during sleep and may sometimes be related to conditions like restless legs syndrome.

Q.
What might be the reason for having hot palms and soles?
A.
Hot palms and soles can be due to conditions that change blood flow and nerve signals in your hands and feet, such as palmar hyperhidrosis or hand-foot syndrome.

Q.
What might be the reason for my legs feeling hot?
A.
Your legs feeling hot can be related to how your body moves blood around to help keep you cool.

Q.
What might cause my hands and feet to always feel hot?
A.
Constantly hot hands and feet might be linked to a condition like erythromelalgia or changes in how your body moves blood to the skin.

Q.
What might cause my palms to feel unusually hot?
A.
Hot palms can happen when the nerves and sweat glands in your hands don’t work as expected, sometimes causing extra warmth or sweating without an illness.

Q.
What should I do if my hands and feet are hot but I have no fever?
A.
If your hands and feet feel hot without having a fever, it’s often a sign of your body’s natural way of regulating temperature, but if it becomes uncomfortable or is accompanied by other symptoms, you should talk to your doctor.

Q.
Why do my legs feel both hot and itchy?
A.
Hot and itchy legs might be caused by changes in blood flow or nerve signals, which can happen in conditions like chronic venous disease or neuropathic itch.
