My left leg is extra swollen in compare to right leg. It is below knee. I never had any kind of excessive pain. It's kind of red coloured. I had CT scan was OK , XRay was ok, MRI report was as follows "III-defined linear hyperintense signal changes are seen in the subcutaneous plane of the anterior and lateral aspects of left leg with few prominent vascular channels s/o subcutaneous oedema with possible varicosities. Advise venous Doppler. No abnormal Contrast enhancement is seen. Mascular planes appear normal. Major vascular bundles are normal. Bones appear normal."
