A blood blister is an accumulation of blood that forms under the skin de to a bruise or a pinch of some sort. Blood blisters have a very unique look and can be easily identified as the sub dermal tissues and blood vessels are damaged without any piercing of the skin. Initially, most blood blisters are extremely painful and, if broken, will let out only a small amount of the contained blood. This not only leaves the skin raw and tender, but also extremely prone to infection. While most blisters will usually go away on their own in about 10 to 14 days, some people are unable to resist the urge to proactively burst them. However, this should be avoided at all costs as it could allow the infection to spread. While blood blisters are very often a result of excessive trauma like pinching, it could also be caused by scalding or burning of the skin, including the effects of sunburn. Other blisters are also known to develop as a result of viral skin infections, fungal skin infections or even allergic irritants.
The best way to take care of a blood blister is to simply let it heal in its own time. There are a few steps that you could take to speed up the process such as soaking a towel in a mixture of salt and ice cold water and apply this on the affected ear to act as a cold compress. In case you notice that the blister has broken, disinfect the wound with the help of an antiseptic mouthwash. The antiseptic properties of garlic are also extremely helpful when disinfecting the wound. Since red meat is known to aid the inflammation of affected areas, it would be a good idea for your daughter to refrain from any intake of red meat for as long as the blister exists. In order to prevent the blister from being unintentionally popped, it should be protected with the help of some medical tape. The tape will act as a strip of second skin that will be a temporary barrier and help speed up the healing process. You could also try to reduce the swelling by applying some Epsom salt mixed with some warm water over the affected area. It is also essential that your daughter avoids turning her head while sleeping to put the entire weight of her head on the affected ear. The added pressure might cause the blister to burst during the course of the night.
