I had a large,red bruise appear on my arm. It was slightly swollen abd felt warm to the touch. I am 52, and on HRT since having a hysterectomy about 18 months ago. Should I be concerned? I have a doctor appointmnent in a couple of weeks. Is it safe to wait until then to mention it to my doctor? The bruise has turned pale brown and is no longer swollen or feverish. There was never any black, blue, yellow, or green coloring. I am about 5 feet 4 inches and weigh about 125 pounds.
