[|Human|] My daughter (20 yrs old) in otherwise excellent health, has a blistery bruise on the back of her left hand near the outermost knuckles. There are small blisters associated with it. It has been there unchanged for two weeks. No known trauma associated with it. Any ideas?
[|AI|]  Dear Sir/Mam, I understand your concerns about the bruises your daughter has. Always a complete workup must be done to exclude serious diagnosis related to platelets and blood clotting factors that might cause this issue. That is why she should do these tests : CBC, PT, INR,PTT, bleeding time, peripheral smear. If all these tests are normal then there is nothing to worry about. I would recommend the following tips also :Immediately after the appearance of the blood patch on your skin put cold compresses for about 20 minutes per hour for few hours, then the next day put warm compresses to help the resorption of the ecchymosis faster. Also, the use of creams containing Alma Vera might help the skin to become healthier and resistant to trauma. Best regards
