cold legs

I have palpitations from time to time sometimes strong enough to keep me awake if they occur at night. tests show a problem with the left ventrical, but is not considered a problem, probably age related.  I had a TIA in 1998 a scan showed several others, I take dypridamole.  I have Reynauds although a blood test came up negative, I always have cold hands and nose, I take nefedepine.

My question is  recently I have had cold legs and feet especially my left leg and foot, I,ve also had a dull ache in this leg for years which isn't always present.  My GP tested the pulse in my feet and couldn't find any, he said 'perhaps that is just me' can anyone shed any light on this for me please. .
