All patients are different, and so are all stories: the patientese has then no fixed rules. What has led me to define it a language is the collective stamp suggested by the words which are repeated much more frequently than other ones.

Here are some of them:

BALL:
 
it is expressed in phrases such as "I feel as a ball" or "I've got a little nut, a little ball". It can be referred either to a sensation or a neoformation, as a cyst, a tumour, a swollen lymph node, etc. It is often related to a sexual problem.
CROSSING, OVERLAPPING, SQUASHING:

they too have a sexual meaning. I have found it in the expressions "I feel a muscle strained", "I see things overlap", "I feel pain when I cross my legs" and so on.

LEANING:
 
by this word it is expressed the lack of an economic, moral and emotional support that one has for a void caused by an affective loss or a disease on points of support such as buttocks, elbows, heels, nape, knees, etc.
CONSTRAINT:
analogous to this word is the sensation of a vicelike grip, a pressure, a compression: it is related to the feeling of being under the authority of someone.
ITCHING
:

referred to the fact that someone is longing to get rid of somebody or of an unpleasant situation s/he can not stand.
