[|Human|] 4 days ago I woke up with a golf ball size lump protruding from the upper right side of my left calf muscle.  It is extremely tender and painful to the touch.   Im not sure what caused it or what to do about it.  I work out 3-4 times a week, could it be some sort of sports injury?  What should I do?
