Brief Answer: Bruising;Senile purpura Detailed Answer: Hello and welcome to healthcaremagic. I am Dr. Kakkar. I have gone through your concern and I have understood it. Significant points in your history are intake of Blood thinners like clopidogrel and Aspirin. I would keep a possibility of bruise/ecchymosis which might have arisen after minor trauma Or insidiously due to scratching. At the age of 75 years, skin becomes becomes thin and atrophic due to loss of collagen and elastin which form the framework of dermis and also support the small capillaries in the dermis. Thus loss of collagen and elastin weakens the dermis and the support that it provides to the capillary walls thus leaving the capillaries prone to fragility secondary to even minor trauma of scratching thus leading to bruising(senile purpura). Both, Aspirin and clopidogrel, interfere with your blood's clotting action. One of the most common skin-related side effects of extended aspirin use is bruising. This effect should not affect you much and might not necessarily be a reason for you to stop your aspirin treatment at normal doses. I think the normal dose of Aspirin that is usually prescribed by doctors for cardiac patients is low dose, 75-150mg once daily. You are definitely taking a higher than usual dose. I would advice that you check with your doctor regarding that. I would advice you an Oral Vitamin C supplement once daily for faster resolution of bruises. You should continue with ONCE DAILY aspirin at low doses 75-150mg. regards
