Hi I am dr Fahim and I will help you with your query I have gone through your question. You have pain in the leg and two lumps one over calf muscle and the other one in the thigh which is present there for years. I need to illicit some more in history and clinical examination. - are the lumps painful? - are they mobile or attached to muscles? - is there any pain in tibial bone and whether it increases with physical activity? Anyhow from available information the lumps appears to be lipoma, which ia a benign lesion, If small no intervention is needed. While the pain appears to be in tibia. If such a patient walks into my clinic without any history of trauma I give pain killers like diclofenac and calcium supplements. Pain usually disappears is a week. If symptoms persists you need further evaluation like x rays of leg. I hope my answer will help you, do rate it if you like it. Regards
