Your pain may not be just much pressure , you could be holding the guitar in a bad position and/or holding the neck incorrectly .
A holding position may be comfortable for a certain style or song bec of the chords used and so , but painfull for other stuff ... The general rule is to have your thumb at the lower back of the neck as if it's facing your middle finger.
