If I'm finding random bruises on my legs what does that mean? There are no lumps just bruises

Bruising. Age? Supplements/foods like garlic, fish oil, gingko? Blood thinner like coumadin (warfarin)? Nsaids like aspirin, motrin, advil, aleve, feldene, etc? Blood vessels become more fragile as we age & can break more easily, causing bruises. Supplements for memory, circulation, heart can thin blood, but not as much as coumadin (warfarin). Nsaids interfere with clot formation. Have fp do CBC for other causes.
