Did you ever find out what the cause of this was? The same thing is happening to my mom and she also has lupus and is wondering what the cause and treatment would be.
Thanks!
Hello,
A blood blister is one of the body’s responses to injury or pressure. Recurrent blood blisters may be found in diabetes and since you are having other symptoms also peripheral vascular disease needs to be ruled out. Even Raynaud’s disease needs an evaluation.
For blood blisters, elevate the hand, give rest to the part, apply cold compresses, soak the blister in Epsom sale and keep the hand bandaged so as to avoid its rupture. If the blister breaks, quickly rinse the area and apply an antiseptic such as neosporin. It is not recommended to break a blister because it may often lead to infection.
Usually it goes away with the treatment. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
