Yes, blood blisters can drain, although often they will heal on their own.
Generally, a small blood blister will dry up and heal within one to two weeks without intervention. However, if a blood blister is large or particularly painful, draining it may provide relief.
Draining a Blood Blister: When and How
-
When to Consider Draining:
- Significant pain.
- Size interferes with activity.
- Risk of accidental rupture.
-
How to Safely Drain a Blood Blister:
- Sterilize: Thoroughly clean the blister and surrounding skin with soap and water. Sterilize a small needle by soaking it in rubbing alcohol.
- Pierce: Gently pierce the edge of the blister with the sterilized needle. Create only a small hole.
- Drain: Allow the fluid to drain naturally. Do not squeeze or force the fluid out, as this can increase the risk of infection.
- Protect: After draining, cover the blister with a clean, dry bandage to protect it from infection. Change the bandage daily.
-
Important Considerations:
- Hygiene is crucial. Always wash your hands thoroughly before and after dealing with a blood blister.
- Watch for infection. Signs of infection include increased pain, redness, swelling, pus, or fever. If you suspect an infection, seek medical attention.
- If you have diabetes or a compromised immune system, consult a doctor before attempting to drain a blood blister yourself.
Draining a blood blister is often not necessary, and letting it heal on its own is frequently the best course of action. If you have concerns, always consult with a healthcare professional.
