. Everyday tasks are very difficult because the blisters often rupture and the blood gets on her clothing, bedding, etc. She once had a similar blister to appear on her lip. Another time there was one in the genital area. She in not on blood thinning medication. She has extreme fatigue, muscle pain and insomnia. Her B-12 was very low and she has received several injections to treat this. Do you have any idea what this could be? Any advice would be greatly appreciated. JB
'A blood-blister usually forms when a small blood vessel close to the surface of the skin ruptures (breaks) and blood leaks into a tear between the layers of skin. This can happen if the skin is crushed, pinched or squeezed very tightly.
Blood blisters should also be left to heal naturally. As with other blisters, if a blood blister bursts it is important to keep the area clean and dry, and protect it with a sterile dressing to prevent infection.
Blood blisters are often painful, and you may wish to apply an ice pack to the area immediately after the injury that caused it. You should apply the ice pack for between 10 and 30 minutes. The ice should not touch your skin directly as this may cause a cold burn, so place a towel over the injured part first.'
