[|Human|] I broke my leg about 13 years ago and where the break was on the inside of the leg there is a bulge that looks like a knot and seems kinda soft to the touch but it is very tender and always painful. Sometimes it swells more than other depending on what shoes I wear and if I have been on my feet for a while. Can you please help. I have had a x-ray and MRI and nothing is showing up.
[|AI|]  Hello, this seems to be a venous malformation present before the injury and which has enlarged due to the trauma. As mentioned its soft and tender. In addition, there is a venous stasis in the affected limb which is the reason for the swelling when tight footwear is used. X-rays will not show anything abnormal. An ultrasound is the most practical test for diagnosis. Elastic stockings will help in compressing the swelling. Surgical options like sclero-therapy and laser treatment can be sought.
