### input:
I have a soft squishy lump, about 1/2 inch diameter on my lower left calf that protrudes only when I am standing. When I am not putting pressure on my leg, there is a slight indentation in that spot. The lump does not hurt, although sometimes after exercise the area aches. I noticed that in the exact same spot on the opposite leg, there is an exact same type of lump, although not nearly as pronounced. I have been an athlete all my life, in great shape, 54 years old, no disease history or current health problems.

Hi, Welcome to Chat Doctor. Based on the facts of your query, as the lump on left calf with slight indentation at the spot, which is painless which appears only on standing and with similar lump on the opposite leg, it seems to be caused from Varicose veins due to short saphenous incompetent vein valves.Throughout the life as an athlete you did not get this, but with aging and addition of increased intra-abdominal pressure, these Long and short saphenous veins have become incompetent lately, which needs to be investigated and investigated after Venous Doppler study and treated from a Vascular Surgeon. So don't worry it. Consult your Vascular Surgeon, after consulting your Surgeon and GP doctor, who would treat this lump with all the care it needs. This reply would resolve your current issues and would reduce your anxiety with it. Hope this reply would help you to plan treatment with your doctor. Will appreciate your Hitting thanks and writing excellent review comments to help needy patients like you. Welcome with any other further query in this regard. Good Day!! Chat Doctor. S. Genl-CVTS
