What Could Be The Cause Of Bruise On Upper Thigh?

Every few days I wake up with a bruise on my upper outter thigh. It s always around the same place. Could I be hitting myself in my sleep without knowing it or could this be a condition? The bruise hurts when I touch it and I usually don t even notice it until I look down when using the restroom.

Hello and welcome to HCM,
The most common cause of bruising is trauma.
If you have a habit of night walking, trauma during night walking cab ve present.
Besides trauma, low platelet count is also a cause of bruising.
Platelets are responsible for forming platelet plug in the blood vessels to prevent bleeding from small blood vessels.
You need to get a complete hemogram and platelet count.
Vitamin K deficiency can also lead to bruising.
Vitamin K is responsible for synthesis of certain clotting factors.
Deficiency of vitamin K inhibits the synthesis of certain clotting factors and thus bruising results.
You need to consult your doctor and get relevant investigations done.

Thanks and take care
