[|Human|] I have a somewhat soft lump on the outside of my right calf - it has been there for several years and nothing shows on an xray or and MRI - it now has some sensitivity - slight burning - if I lay on the right side it will awaken me w/an unusual feeling - any thoughts?
[|AI|]  Hello! Thank you for the query. This lump is most likely a varicose vein. Due to increased venous blood pressure in the leg (due to gravity), veins in this are got enlarged and result with soft lumps. It can be less visible when lying down and more visible when standing for a long time. Pain in such lump area can indicate blood clot inside. That is why, I suggest you to consult a surgeon (in next day). Doppler's ultrasound should be done and surgery scheduled in case of veins insufficiency. Hope this will help. Regards.
