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.
