good evening, from the Uk, i have awful circulation in my legs, even though i am only 45, this is due to an addiction to illegal drugs in my youth!! i developed an arterial ulcer last year on my right leg after being bitten, then scratching said bite till i tore through the skin!! Anyway trying to cut a long story short....today i have immense pain in my left ankle, as if i sprained it but i haven't. I don't want to bother my doctor, as i feel i see enough of him for someone my age x can you enlighten me at all and should i be worried? thank you x
