Hi,Dear,Welcome to HCM. Based on the facts of your query,You seem to suffer from-hard bony lump on the sides of the leg below knee of left leg.Cramps in the lower leg and X-ray study after the
CT scan study,indicates something boney
osteophyte of the knee joint,causing the issues with the lump below knee.
This lump could be MB
Cyst or could be Osteolcastoma of upper end
Tibia / or could be osteophyte of the knee joint.
Arthroscopic removal of the MB Cyst or
Osteotomy of the tibia with Bone graft would resolve the lump besides the knee.
CT and USG would fix the diaganostic ambiguity and doubts.
HOpe this reply would help you to plan further treatment with your doctors.
