A few months ago I found approximately a nickel size bulge on my left leg, ride side of my shin. I'd say its about half way between my ankle and knee. There is a vein in that same location. At that time there was no pain, just inflammation. I figured if it got bigger I'd start to worry about it. Well, the size hasn't changed much but tenderness, and now pain, has changed. Two nights ago I woke up with what I thought was a cramp in my left foot. I tried to walk it off but I could barely walk at all. It hurt to walk. When I touched the area where the bulge is I noticed it hurt, especially the bone area. I took some advil and that seemed to do the trick. During the next day there was no pain at all. I thought it was just an anomaly. Last night it happened again. It felt like a cramp and I could barely walk on the left leg. This time it was a bit larger but not that much. I did the same thing, took the advil and finally fell asleep. Now, my foot still hurts but I can walk okay. The bulge area is sensitive and hurts when I push it.

So, is it a vein issue or some other possible issue? I'v also noticed that on the opposite side of the leg there is a bruise but I guess that could have been there for some other reason.
