Thanks for posting your query.
Area over the thigh with spontaneously appearing bruise
without any history of trauma is indicative of a bleeding disorder
. In bleeding disorder there is a tendency to bruise easily due to an increased fragility of the blood vessels.
Excessive intake of food stuffs like fish oils, ginkgo biloba
, ginger or garlic can precipitate such events.
Spontaneous bleeding needs to be investigated with coagulation and bleeding profiles . It is best to see your doctor as soon as possible to avoid further complications.
Wishing you good health.
