This is Dr. David
taking aspirin will make you much more prone to brusing.
a small bump on your shoulder or hip or leg can cause bruising when you are taking aspirin.
aspirin defunctionalizes the platelets in your blood for a week.
and decreases blood clots this way.
I wouldn't worry too much about these bruises.
you can let your doctor know about them at your next meeting.
do make sure you take the aspirin with food in your stomach to protect your stomach and with plenty of water.
