About 2 months ago, I noticed what I thought to be a bruise on my left ankle. About 2 days later, I noticed that my ankle was swollen. I thought nothing of it since it didn't hurt or anything. Over the last 2 months, I have noticed that these "bruises" seem to be growing, and multiplying. Some of them are even hard to the touch. And still, they do not bother me. I don't notice them until I look at my leg, that's when I notice that I have more. I have been to my doctor, he ran a blood test. My blood test came back normal. He said that he has no idea what they are. He said that it's odd because my whole left leg is about 3-4cm bigger than my right leg. He said that they are not bruises because they aren't tender and don't bother me. And said that they can't be hives because they are hard. He scheduled another appointment with me in 2 months, but said that if more appear that I am to come in asap. I am scared. If he didn't know then, and wanted to wait 2 months, then why am I to come in asap if more appear? When I went and saw him about a week ago, I had 6 "bruises"....I am now at 10 "bruises". What could possibly be wrong with me?
