Question: Blood under the skin

 FINALFOLD30 - Tue Oct 27, 2009 3:35 pm

I noticed a small V shaped blood blister on my arm the other day and it has me concerned. I am 30 years old and in good health and this mark on my arm almost looks like a small hickie that would normally appear on the neck. It is starting to dissapear but I am wondering what can cause this type of mark? Is it safe to not seek medical attention? It doesn't hurt or cause any annoyances but I just havent seen this type of blood blister before so I wanted to see if someone could give me an idea of what it is and whats it cause from.

User avatar Hello,Extravasation of blood in to the skin can be a very simple one like a minor trauma.Rarely other problems like scurvey due to vitaminC deficiency and blood cell related diseases mostly due to platelet related diseases,blood vessel disorders,and bleeding disorders like hemophilia.Lack of vitK and liver disorders do cause bleeds in the skin.Allergic purpuras are also well known.Drug induced purpuras due to heparin are also met in practice.Old people get senile purpuras.With your good general health there may not be much to worry,all the same a CBC may be required just to make sure.Ok?Bestwishes.
