[|Human|] I have a hard lump on my left calf that I noticed in January 2014 after a run and don t know what it is. Went to my Dr and he was not familiar with it as he had never seen a lump on a calf before. Then I had sonogram and I was told they dint see anything malignant. Im a 34 yo male and take Bystolic and albuterol.
[|AI|]  Hi. As per your history of finding the lump on the calf after a run indicates me for the most probable diagnosis of herniation of the muscles through a small tear through its covering (herniation). This can be nicely seen on sonography if examined with a high frequency probe. You may please consult an Orthopedic surgeon to get a proper diagnosis and management, may need to require a small surgery. Please keep me posted about the results f diagnosis and treatment.
