How to get rid of a blood blister
Just like clear blisters, the vast majority of blood blisters will heal and disappear within a week or so.
However, Dr Lee noted: “Blood blisters can also get secondarily infected. If a blood blister seems to be enlarging, has pus inside it, has a red ring around it, you develop a red streak up your arm (lymphangitis), or you develop a temperature and feel generally unwell, always seek medical help without delay.”
People with underlying health conditions such as diabetes, HIV, heart failure or venous leg ulcers are more at risk from infection of a blood blister.
There are some things you can do to speed up the healing of a blood blister and prevent infection.
Dr Lee said: “Always wash your hands before touching your blister and cover it with a padded dressing – your pharmacist can advise which one but usually a hydrocolloid dressing is recommended.
“These provide a clean, absorbent environment for wound healing to take place.
“You may also want to elevate the affected area. Wrap it in a towel, and apply ice to the area, if it is swollen.”
