And where does the pain come from in terms of feeling?
Yes localised
Interpreted as coming from the skin overlying the point of irritation
In the right hypochondrium
Diaphragm is innervated by which nerve? Which contain nerve fibres from?
These fibres also receive sensory input from the skin over the?
Therefore the brain interprets painful stimuli from the diaphragm as if its coming from the ?
Phrenic
C3-5
Shoulder
