I understand your concern.
Redness of the legs is likely caused by the peripheral vascular disease.
The color change is due to the delayed blood flow in the legs.
Staying off the feet does help with the symptoms.
However, further evaluation is necessary to locate the blockage in the leg blood vessels.
This is probably the reason why he also had the toe ulcers --and the toe needed to be removed ( due to the decreased blood circulation).
Although not urgent if there is no pain or swelling, this should be evaluated by a vascular surgeon soon.
In case, there is blockage in the blood vessel, bypass graft surgery may be required to establish the blood flow to the legs.
