Gout can feel like a broken toe , it is that painful and can be a very sudden onset .
But it is usually in the joints (especially the 1st toe ) though can occur anywhere .
Is there a solid thickening of skin?
Are there tiny blood vessels ?
Wet the skin for a better view . Do the tiny lines of the skin run through it or are they pushed aside?
It could also be a foreign body , possibly resulting in a localised but deep infection.
Chilblain is a possibility , I have seen some really bad ones this year but mainly patients who get them every year (and I do start advicing them in Sept , they are all Meh weather is nice ......until the cold snap)
Patients who have a history of micro circulatory problems or patients from warmer climates in their first UK winter
Don;t use any acid based products , you;ll have a mess of mascerated skin.
You can try warm salt water footbaths (soothing and can draw things to the surface and antiseptic)
Put a ring of felt round to keep the pressure off
Get thee to a Podiatrist .
Think back to when you felt the pain first . What relieves it. What worsens it . Check ALL your shoes, slippers, socks for holes and seams .
