<s>[INST] Hi, I have a 1" wide by 1/2" protruding lunp on the left side of my lower leg not in my calf muscle but next to it closer to the side/front of my leg.  It doesn't hurt and is not discolored and is hard.  I just got it recently.  What can it possibly be? [/INST] hi.do you have any history of trauma? how long has it been there? do you have any other symptoms aside from the lump?it is best if you consult w a general surgeon or an orthopedic surgeon for physical examination. that "lump" might just be a cyst or a lesion with underlying pathology. further diagnostics (such as MRI or xray) would be directed accordingly.hope this helps.good day!!~dr.kaye </s>
