I have an appointment set for Tuesday, June 24th, however... I have a bit of anxiety and don t know if I am over analyzing or worrying over this. Last week I was obsessing over my freckles...color, shapes, etc. I am a fair skinned red head, so I have had freckles all my life (I am 27). But a show on tv got me paranoid. While I was looking at my freckles I just so happened to feel and find a knot on the inside of my elbow. If you were to turn your palm up and l look at your elbow crease, it is on the side of my arm closest to my body, just above the crease I cannot tell if is movable or fixed in position. It sort of feels movable, but I am kind of overweight and have fat in my arms, so it is confusing. It feels round. Of course when you search online, almost every symptom could be the dreaded C word, and I start feeling panicked. I have two small children and that is not what I want to worry about. I m thinking it is nothing, and quite possibly scar tissue from maybe an IV I had several months ago while having a heart issue. But, is it possible it is something more serious, such as melanoma, or a symptom of disease?
