3 classes of Nociceptor Pain.
by the Institute for Clinical Systems Improvement
musculoskeletal pain: pain that affects the muscles, ligaments and tendons, along with the bones
inflammatory pain: Inflammatory pain is precipitated by an insult to the integrity of tissues at a cellular level. This can happen with penetration wounds, burns, extreme cold, fractures, arthritis, autoimmune conditions, excessive stretching, infections and vasoconstriction. During inflammation a complex neuro-immune interaction results in primary hyperalgesia. (Rheumatoid and arthritis)
mechanical/compressive pain (using back pain): irritation or injury to the disc, the ligaments or the muscles/ nerve roots that leave the spine are either irritated or pinched
