I think I might have a blood blot.?

So I was sitting in my living room and I noticed that my legs looked a little swollen by my shins right below my knee. My mom had 3 blood clots a year ago and since then I have been TERRIFIED of getting one myself. I have a panic disorder so when anything out of the norm happens to my body it freaks me out... There isn't much pain where the swelling is, the one leg hurts a little but it could be from me poking it. Anyways can someone help?
