Hello ma am and welcome to HCM Since you have not mentioned any personal history of heart disease, Diabetes, High BP etc, do note that these may indirectly cause symptoms of bruising and skin changes. In your case age can be a common reason as the skin and its blood vessels become very fragile and can bleed on slight pressure, possibly due to exercise, tight jewellery or a wrist watch.etc Are you on any blood thinners, aspirin etc? or any other medication? Do you see bruises elsewhere? I suggest you check your blood levels for anemia, diabetes and cholesterol levels as well as liver function. And if you haven t recently visited your GP, do go in for a general wellness check, given your family history. If the bruises are symptomatic, with itching, burning or pain, do see a dermatologist to rule out vascular diseases. As of now, when you have bruises, you can apply thrombophob ointment. They will otherwise resolve by itself. Hope this helps. Always better to check when bruises are repititive.
