It is generally not recommended to pop a blister, as it can increase the risk of infection and slow down the healing process. However, if the blister is causing a lot of pain or discomfort, and if you need to continue using the affected area, you may consider draining it safely.

Here are some steps to follow:

  1. Wash your hands and the blister with soap and water.

  2. Sterilize a needle or pin by holding it over a flame or soaking it in rubbing alcohol.

  3. Gently puncture the edge of the blister, and let the fluid drain out. Do not remove the overlying skin.

  4. Apply an antibiotic ointment and cover the blister with a sterile bandage or dressing.

It is important to keep the area clean and dry, and to monitor it for signs of infection, such as redness, swelling, or pus. If you develop any of these symptoms, or if the blister becomes more painful, seek medical attention.
