Obese people may be more sensitive to pain

The obese patients showed a greater physical response to the electrical stimulation than did the non-obese people, both before and after the training session. This indicates they had a lower tolerance for the painful stimulation despite reporting, in questionnaires, that they felt no more pain than non-obese people.
