Understanding Blood Blisters on Toes
Blood blisters on toes can be painful and concerning. However, they are relatively common and usually not a major cause for alarm. Let's take a closer look at what causes blood blisters on toes and how to treat them.
What Causes Blood Blisters on Toes?
Blood blisters on toes form when blood vessels under the skin's surface break and leak fluid. This fluid accumulation under the skin results in a blister filled with blood instead of clear fluid. There are a few potential causes of blood blisters on toes:
- Friction - Tight-fitting or rubbing shoes can cause friction against the skin that leads to blood blister formation.
- Blunt trauma - Dropping something on your toe or stubbing it can cause enough damage to form a blister.
- Pinched skin - If the skin on your toes gets pinched, like when putting on socks, a blood blister may develop.
- Toenail issues - Ingrown toenails or fungal toenail infections can cause irritation and blisters.
Who is at Risk for Blood Blisters on Toes?
While anyone can get a blood blister on their toe, some factors that increase risk include:
- Wearing tight or ill-fitting shoes that rub against the toes
- Participating in sports or activities where toes get irritation or impact
- Having an underlying toenail issue like an ingrown nail
- Having thin skin that is more prone to damage
- Having poor circulation in the feet
What Do Blood Blisters on Toes Look Like?
A blood blister on the toe is a small raised bump or lesion that looks filled with blood instead of clear or yellow fluid. Common characteristics include:
- Size of a pea or larger
- Round, raised shape
- Filled with dark red or purple blood
- Minimal pain unless rubbed directly
- Located on toes, especially big toe, corners of nails, or webbing between toes
Treatment for Blood Blisters on Toes
In most cases, blood blisters on toes will go away on their own without needing medical treatment. However, you can take these steps to help manage blisters:
- Rest the foot - Take pressure off the affected toe by limiting walking
- Apply ice - Use an ice pack wrapped in cloth for 10-15 minutes to reduce swelling and pain
- Bandage - Wrap gauze or small bandage around blister to cushion it
- Wear loose, breathable socks and shoes - Avoid tight shoes that rub on blisters
- Keep clean - Gently clean with soap and water if broken to prevent infection
- Leave intact - Do not try to pop or drain blood blisters
- See a doctor - If signs of infection like increasing pain, redness or pus, seek medical care
When to See a Doctor
In most cases blood blisters heal on their own, but it is wise to seek medical care if:
- The blister does not diminish in size after a week
- Signs of infection develop like pus, foul odor, increasing pain or redness
- The blister bleeds or seems very deep
- You have diabetes or circulatory issues that affect wound healing
- You have recurrent blood blisters on toes without clear cause
A podiatrist can properly diagnose the underlying cause and provide treatment options, including draining very large or painful blisters. Seek prompt care if you have any concerns over a blood blister not healing properly.
Causes of Blood Blisters Under Toenail
Blood blisters under the toenail, called subungual hematomas, have a few common causes including:
- Blunt trauma - Dropping something on the toe or stubbing it can damage the nail bed.
- Tight shoes - Shoes pressing on the toe can put excess pressure on the nail.
- Injuries - Damaging the nail through sports or accidents.
- Nail problems - Ingrown nails, fungal infections, nails that are too long.
- Medical conditions - Complications from diabetes, anemia, psoriasis.
Symptoms
Signs of a subungual hematoma include:
- Collection of blood under part or all of the toenail
- Toenail appears bruised and purplish-red
- Pain or throbbing in the toe
- Difficulty wearing shoes due to tenderness
- Nail may thicken, crack or fall off eventually
Treatments
Treatment options for blood blisters under toenail:
- Warm soaks - Help relieve pain and soften nail.
- Trimming nail - Relieve pressure by conservatively cutting nail.
- Draining blister - Sterilize needle to gently pierce and drain.
- Antibiotics - Prescribed if infection develops.
- Removal of nail - Severe cases may require full or partial nail removal.
- Preventative tips - Wear properly fitting shoes and trim nails.
See a podiatrist promptly if the blister is severe, spreads, or does not seem to heal. Diabetics and those with circulatory issues should seek medical care.
Blood Blister on Bottom of Foot
Blood blisters can sometimes develop on the bottom or side of the foot. Common causes include:
- Friction from shoes or socks rubbing the skin
- Pressure from uncomfortable shoes or walking long distances
- Stepping on sharp objects like tacks or rocks
- Burns from hot surfaces
- Blunt trauma from dropping objects on feet
Treating Blood Blisters on Feet
To help manage painful blood blisters on the bottom or side of feet:
- Avoid walking barefoot to prevent irritation
- Wear properly fitting, comfortable shoes with socks
- Clean gently with mild soap and apply antibiotic ointment
- Cover with gauze or bandages to cushion
- Apply ice packs for 15 minutes a few times per day
- Keep feet elevated when possible to reduce swelling
- Use over-the-counter pain medication as needed
- Watch for signs of infection like increasing pain, heat, redness
See a doctor promptly if the blister does not seem to be healing within a week or becomes infected. Those with diabetes or circulation issues should be vigilant about foot injuries.
When to Go to the Emergency Room for a Blood Blister
Most blood blisters can be cared for at home. However, go to the emergency room promptly if:
- The blister causes severe, throbbing pain
- It occurs with other serious foot injuries like broken bones
- Signs of a limb- or life-threatening infection are present
- You have diabetes and the blister does not seem to be healing
