I am 58 years old male.I had one hip replaicment surgery in April this year and another hip replaicment surgery was after 4 weeks. I started bruising aproximetly year ago after light bumping ( on my legs and arms ). I am takeing baby aspirin for last 4 years, blood pressure medicin Exforge onse a day, Lasix for swollen legs and triple strength fish oil. After any bumping I am bruising. How to prevent it? Can my medicine be one of the reasons? How to treat this and how to heal my skin?
