So just home after a visit to GP about the pain, coldness, itch, swelling and change of colour to my feet. Felt my feet and said they felt warm to her (I had been wearing flight socks and ugg boots) to walk to the Drs and said that our mind believes that our feet are cold but when we touch them they are actually warm. Have to go for physio but I have never felt so stupid in my life.
Thanks to everyone for their advice and comments.
