Hi, Years Ago I Had A Bad Case Of Cellulitis

Hi, years ago i had a bad case of cellulitis in my right leg (shin & Calf) After having if treated it left bad scarring along with poor blood circulation through out my entire leg. I also have noticed that now Im having problems walking distances & even standing too long. I cannot walk or stand for more than 15 minutes tops, which results in me having to sit down for a few minutes to relieve pain & tiredness. I have been over weight for for many years & do realize that this is part of the problem but dont think its the only problem thats causing this pain & tiredness. It feels as though Ive run a marathon & my muscles ache like hell (pardon the expression) Would the poor blood circulation have anything to do with this problem Im having? Your answers would be appreciated. Regards Fred...
