Pain:

The uncomfortable, subjective sensory and emotional experience associated with actual or potential tissue damage.

Causes of pain:

Pain can be acute or chronic.

Acute pain is described as nociceptive. It originates in somatic tissue, like skin, bone, etc or visceral tissue, e.g. organs

Chronic pain is functional and neuropathic pain. Functional pain can be described as fibromyalgia, IBS, tension-headaches etc. Neuropathic pain is due to nerve damage or injury.

Why do different people experience pain differently?

The sensitivity and tolerance people show towards pain varies predictably according to several factors, including gender, ethnicity, personality and culture, all interacting, overlapping and playing out in the tissues and synapses of the body.

Pain management

The primary aim of acute pain management is to provide treatment that reduces the patient's pain, with minimal adverse effects, while allowing them to maintain function. A secondary aim is to prevent acute pain from progressing to chronic pain
