The purpose of the study is to discover at least two distinct Musculoskeletal pain subtypes. These types are caused by different brain-and-immune system signals that affect how the body feels pain, and they are also shaped by a person's biology, psychology, and social environment. Aim 1. We want to sort adolescents and young adults with long lasting muscle and bone pain into two different groups. To do this, we will look at participants' childhood medical histories, past treatments, when their pain started, the sex they were assigned at birth, what their pain feels like now, tests of how their body senses pain, and immune system markers found in their blood. We think we will find at least two different types of chronic pain groups, plus one group of patients who had a higher risk for pain (because of a rheumatic disease or past surgery) but never developed long term pain. Aim 2. We want to find out if certain patterns of inflammation in the body change how nerve cells react to pain. Aim 3: We want to understand how different biological, psychological, and social factors are connected to the chronic pain groups we identified. We think we will find certain mental, behavioral, and social risks-as well as protective factors-that help explain why some people develop long-lasting pain and others do not. We expect these factors to play different roles in each pain group, including the group that does not develop chronic pain.

RECRUITINGConditioned Pain Modulation (CPM) Profile (Pressure)
CPM is defined by the change in pressure thresholds (increase) before and during cold immersion. Pressure thresholds will be measured using an algometer.
Time frame: Baseline
Conditioned Pain Modulation (CPM) Profile (Heat)
CPM is defined by the change in heat pain intensity (decrease) before and during cold immersion. Heat stimuli will be delivered by a thermode and pain intensity measured by participant self report on the visual analog scale.
Time frame: Baseline
Temporal Summation (TS) Profile
TS is defined by the change in mechanical pain intensity (increase) after exposure to a series of pinprick stimuli. Pain intensity will be measured by participant self report on the visual analog scale.
Time frame: Baseline
