Itchy feet at night usually come from dry skin, athlete’s foot, or a reaction to socks, soaps, or lotions. Most of these clear with simple changes. Some causes are serious, including diabetes, nerve damage, liver disease, and pregnancy, so itch that keeps coming back deserves an evaluation.
In our Florida offices, the feet that itch most at night are often the ones that spent the day in closed shoes in humid weather, or the ones that dried out in air conditioning.
What causes itchy feet at night?
Most cases start in the skin. Dry skin, fungal infection, and contact reactions cause most of the mild cases we see.
Dry skin. Air conditioning dries indoor air, and heel and sole skin loses moisture quickly. Flaking, rough heels are a common sign.
Athlete’s foot. This fungal infection thrives in warm, damp spaces, so it often flares after a day in closed shoes or time at a pool. Look for itching between the toes, peeling, or odor. Harvard Health notes that recurring cases can take several weeks to months to respond to treatment. See our athlete’s foot guide.
Socks, soaps, and lotions. Contact reactions cause red, bumpy patches where the material touches the skin. Common triggers include fragrances, sock dyes, and some laundry products. The rash usually improves once the trigger is removed.
Why do your feet itch more at night?
If the problem is cold feet rather than itch, the causes are different. Cold feet at night usually involve circulation or nerve function, so they need their own evaluation. Read our guide to cold feet at night for those causes and warning signs.
Can diabetes cause itchy feet?
Yes, through dry skin and nerve damage. Diabetic nerve damage can reduce sweating, which leaves the skin dry, thin, and prone to cracking. Sensory neuropathy can also reduce the feeling that would tell you a sore is forming.
That is why scratching is risky for people with diabetes. A scratch you can’t feel can turn into an ulcer. If you have diabetes and your feet itch, get them examined rather than treating only the itch. Read more about peripheral neuropathy and cracked feet with diabetes.
Can pregnancy cause itchy feet?
Yes, and this cause should not wait. Intrahepatic cholestasis of pregnancy usually appears in the third trimester. It causes itch, most often on the palms and soles, that is often worse at night. It can occur without a rash, so many people don’t connect it to the liver. Diagnosis rests on blood tests for bile acids, and treatment is supervised because the condition can affect the baby.
If you are pregnant and your palms or soles itch intensely, call your obstetric provider the same day.
Can medications cause itchy feet?
Yes. Opioid pain medicines and chloroquine are among the best-documented causes. Hydroxychloroquine can cause itch less often. Some antibiotics also list itch as a side effect.
Do not stop a prescription on your own. Call your prescriber or pharmacist, and bring a full medication list to your visit, including over-the-counter sleep aids.
How do you relieve itchy feet at night?
Start with the basics. Moisturize with a fragrance-free cream right after a shower, while the skin is still damp. Keep your bedroom cool and wear breathable cotton socks to bed. For intense itch, apply a cool, damp cloth for 10 to 15 minutes.
A 1% hydrocortisone cream can help for short periods. The OTC label says to stop and ask a doctor if symptoms last more than 7 days. Keep it off open cracks.
A short cool soak with colloidal oatmeal has published support for itch from dry skin. Epsom salt soaks have limited evidence. They can dry the feet, so skip them nightly.
Avoid diphenhydramine sleep aids if you are 65 or older. The AGS Beers Criteria lists it as a medicine to avoid in that age group because of confusion and falls.
Should you be worried about itchy feet?
Most itchy feet are a skin problem that responds to home care. This table shows how the common causes differ.
| Cause | Typical Symptoms | Severity | When to See a Doctor |
|---|---|---|---|
| Dry skin | Tight, flaking heels; itch worse in bed | Mild | Itch lasts past two weeks despite daily moisturizing |
| Athlete’s foot | Itch between toes, peeling, odor | Mild to moderate | Spreading, cracking, or nail changes |
| Contact reaction | Red or bumpy patches where material touches skin | Mild | Blisters, oozing, or no improvement after removing the trigger |
| Eczema or psoriasis | Thick, scaly, or cracked patches on soles or ankles | Moderate | Patches spread, crack, or disrupt sleep |
| Diabetic neuropathy | Itch with tingling, burning, or reduced feeling | Moderate to urgent | Any cut, blister, color change, or loss of feeling |
| Medication side effect | Itch starting after a new drug, may spread | Varies | Rash, swelling, or trouble breathing needs emergency care. Otherwise call your prescriber before stopping. |
| Liver disease | Itch with fatigue, dark urine, or yellow eyes | Urgent | Any of these signs, promptly |
| Pregnancy cholestasis | Intense itch on palms and soles, often without rash | Urgent | Same-day call to your obstetric provider |
| Iron deficiency | Restless legs, fatigue | Moderate | Blood test to confirm |
Itch that comes with red spots has its own set of causes, covered in our guide to red spots on feet.
Book a visit promptly if any of these apply:
- The itch lasts more than two weeks despite daily moisturizing
- It keeps you awake most nights
- It spreads to your hands, legs, or whole body
- You see cracks, open skin, blisters, or sores
- One foot is clearly worse, or you notice color changes
- You have diabetes and any change in your feet
- You are pregnant and have intense itch on your palms or soles
- You have yellow eyes, dark urine, or unexplained fatigue
Seek urgent care for swelling of the face or throat, trouble breathing, or fast-spreading redness with fever.
When should you see a podiatrist about itchy feet?
See a podiatrist first when the itch centers on the feet, especially with nail changes, cracking, or diabetes. We examine the skin, nails, and sensation, and we prescribe antifungal or stronger topical treatments when needed. If the findings point to a whole-body cause, we coordinate with your primary care doctor.
A typical visit follows four steps:
- We take a history covering when the itch started, what makes it worse, and any new medicines or products.
- We examine the skin between the toes, the soles, the nails, and sensation in both feet.
- We order or coordinate blood tests when the picture suggests a systemic cause.
- We leave you with a plan covering what to change at home and when to return.
If your feet itch enough to disrupt your sleep, book a visit at our Boca Raton office or Boynton Beach office, or see our team in Coral Springs. You can request an appointment online or call (855) 550-3338.

Frequently asked questions about itchy feet at night
Q: How long should itchy feet last before I see a doctor?
A: If the itch lasts more than two weeks despite daily moisturizing and fresh socks, book a visit. Come in sooner if the itch keeps you awake or a rash spreads. People with diabetes should be seen early, because nerve damage can hide injuries.
Q: Can itchy feet be a sign of liver disease?
A: It can be, though it is less common than skin causes. Liver-related itch often comes with fatigue, dark urine, or yellow eyes. Those signs need prompt blood testing.
Q: Is Epsom salt good for itchy feet?
A: The evidence is limited. Epsom salt soaks can dry the feet, and most of any benefit probably comes from the warm water. A cool soak with colloidal oatmeal has better published support for dry, itchy skin.
Q: Should I stop a medication if my feet itch?
A: Not without medical advice. Call your prescriber or pharmacist first, and bring a full medication list to your visit.
