We are leaving tomorrow for a cruise and I am concerned about an area in the side of my lower leg-about 1 1/2 to 2 in inch circle. Raised and very tender to touch. Seems a little hard when you lightly touch it. The area has gotten smaller since this morning, but now it definitely hurts. Looked up what it could be..blood clot. But not sure. What could it be. Oh, yes, this morning it was quite warm to touch. I am 82, 125 lbs. VERY active- gym, yoga...I do not sit, I am not over weight. If that helps you.
