Although some injectors use the veins in the feet , there are several factors that make them an unsuitable choice for anything other than occasional use :
o Venous blood flow in the feet is slow . o If local infection occurs , this can lead to loss of mobility . o Injury to the feet may be slower to heal than in other areas , especially in individuals with already damaged circulation . o Fungal infections of the feet are common for most people . If there is a need to wear shoes his may encourage or compound problems of infection . o As with the legs , injections in the feet should be done as slowly as possible to prevent overloading the vein . o The superficial veins of the feet tend to wobble ‘ when people try to get a needle in them , and this can result in more frequent missed hits ‘ and vein damage .
