Factors influencing time course of pain after depot oil intramuscular injection of testosterone undecanoate, the discomfort around the injection site after an IM injection was found to be less severe in men who are older and more obese. Age and body weight are the two predominate factors that influence a painful injection experience.
While it can be expected that any intramuscular injection will cause some degree of discomfort, the severity, duration and experience by each patient will vary. In a study by O Svendsen et. al. Intramuscular injections and muscle damage: effects of concentration, volume, injection speed and vehicle, it was revealed that small volume of concentrated solution vs larger volume of. Less concentrated solution produced less muscle damage. The speed by which an injection is given into the muscle was not factor.
