Hello.
Thanks for writing to us.
Spontaneous appearance of bruises without any history of
injury in the area can be due to many factors like anti inflammatory intake,
autoimmune disorders,
platelet dysfunction, viral illness, etc. He needs to consult a physician to find out the cause.
I hope this information has been both informative and helpful for you.
Regards,
Dr. Praveen Tayal
