Hello Dear,
It seems that if DVT is ruled out then probably then it might be superficial thrombophelibitis that is inflammation of veins and surrounding tissue.
Does she have fever also?
Is she on antibiotics?
Any other associated symptoms?
Discuss this with the treating doctor.

Hello Dear,
I can understand your problem well.
The discoloration and swelling might be due to thrombosis.
It can cause permanent damage to the leg, known as post-thrombotic syndrome.
Significant number of patients develop pooling of blood due to permanent irreversible damage in the affected leg veins and their valves.
This results in chronic leg pain, fatigue, swelling, and, in extreme cases, severe skin ulcers. Blood thinners (anti coagulants), clot removal via interventional catheter-directed thrombolysis in selected cases can improve quality of life and prevent the debilitating sequela of post-thrombotic syndrome.
Consult your orthopedician for the further course of action.
Best.
