[|Human|] Doctor, I wake up sometimes with a little purple bruise on the inside of my upper arm smaller than a pencil eraser. It doesnt happen every day but always in the same area of both arms one at a time. What could it be? We have spiders and cockroaches around here. No bed bugs seen. The bruise goes away in about 4 days. Thanks, Ann
[|AI|]  Hello, I understand your concern. I am Chat Doctor, infectious diseases specialist, answering your query. In my opinion you should not worry about bugs. It is likely that it is from the purpura. Purpura occurs because of thrombocytopenia. The cause of which is not known. As platelets decreases this purple bruise occurs. There are many causes of purpura exact can only be known if completed general examination has performed which can only happens. I advise you should visit the hematologist to get your complete examination done. I will be happy to answer your further concern, you can ask me on bit.ly/ Chat Doctor.  Thank you.
