An exaggerated or irrational fear of objects on the left side of the body is called Levophobia. This is fairly uncommon and is not to be confused with other fears concerned with the left, notably sinistrophobia which has a markedly similar meaning but is concerned with left-handedness and is not bodily oriented.
Levophobia has been noted as a typically right handed fear where the non dominant side feels irrationally vulnerable. In some cultures, being left-handed is seen as a taboo and some children are taught to learn to be right-handed and this can be a source of the phobia. Some persons might also have deformities in the left side of their body thus their fear of imperfection has contributed to this phobia.
Sufferers of this Phobia can be assumed to be displacing a deeper issue to a non threatening fear. It is safe to say that the left side of the body may be at best a clue for the therapist to work from.
Sufferers may also display sinistrophobia but not necessarily visa-versa. As with all psychological disorders the details and cause can vary greatly in detail from sufferer to sufferer. Medical treatment is rarely needed.
