A little island with a warm breeze

Can anyone offer some insight here? I’ve noticed my right foot feels significantly warmer than my left. I usually deal with poor circulation in my legs and they're almost always freezing. Any advice would be greatly appreciated. Thanks in advance.

You really ought to schedule an appointment with a vascular surgeon.

It’s quite simple, really—when your feet start feeling colder than usual, it’s often a sign that blood flow is being restricted by arterial issues.
A specialist will likely send you in for some diagnostic testing—most probably a color Doppler ultrasound to get a clear picture of what's happening.

It is vital to address these arterial concerns immediately; after all, isn't it much easier to manage small changes before they escalate?
If significant blockages develop within the arteries, surgery can very quickly become the only viable option.

It looks like my foot is running a bit warm. There’s some slight swelling under the toes on the sole, though you can barely notice it.
No pain or anything, just noticed one foot felt warmer than the other at first. Then came the swelling—I suspect it's from wearing those uncomfortable Doc Martens—but the heat seems to have subsided now. I still need to go see my doctor, though.
