[|Human|] Hi. I have small lumps in my calves when I stand. They disappear when I sit down or if I take my weight off of one of my legs they disappear in that leg. I ve noticed that some other guys at my gym have the same thing. It must be harmless but I m curious to know what they are exactly.
[|AI|]  Hi! This is very common a complaint especially in people who stand for long hours due to occupational requirement and in people who have some problems with valves of the lower limb veins! These are called varicose veins, and you need a Doppler study for evaluation of the veins affected, its severity and the status of valves! A constant compression bandage is generally recommended especially in day time to control progression of the disease otherwise it might need a major leg surgery!Therefore, please see a general surgeon in your locality for a better future health!regards,
