Conditions Library

Explore trusted, evidence-informed information about chronic pain and invisible illnesses — from AMPS and CRPS to fibromyalgia, EDS, and dysautonomia.

Connective Tissue

Ehlers-Danlos Syndrome (EDS)

A group of inherited connective tissue disorders causing joint hypermobility, skin changes, and tissue fragility — frequently overlapping with chronic pain and dysautonomia.

Fibromyalgia

A chronic condition causing widespread pain, fatigue, sleep disruption, and cognitive difficulties — driven by central nervous system sensitization.

Amplified Musculoskeletal Pain Syndrome (AMPS)

A condition where the nervous system amplifies pain signals beyond what's expected — causing real, intense pain without visible tissue damage on standard tests.

Complex Regional Pain Syndrome (CRPS)

A specific, localized form of amplified pain — usually affecting one limb after an injury — where the nervous system produces severe, persistent pain disproportionate to the original trauma.

Postural Orthostatic Tachycardia Syndrome (POTS)

A form of dysautonomia where standing causes an excessive heart rate increase, leading to lightheadedness, fatigue, and brain fog — often overlapping with chronic pain conditions.

Myalgic Encephalomyelitis / Chronic Fatigue Syndrome (ME/CFS)

A chronic, complex illness marked by profound fatigue, post-exertional malaise, and cognitive dysfunction — often worsening after exertion and frequently overlapping with chronic pain and dysautonomia.

Invisible Illness

Myalgic Encephalomyelitis / Chronic Fatigue Syndrome (ME/CFS)

A complex chronic illness characterized by profound fatigue, post-exertional malaise, sleep dysfunction, and cognitive difficulties.

Central Sensitization Syndrome

A condition where the central nervous system amplifies pain signals, causing widespread, persistent pain and hypersensitivity.

Chronic Migraine

A neurological condition causing 15 or more headache days per month, often with severe pain, nausea, and sensitivity to light and sound.

Invisible Illness

Endometriosis

A condition where tissue similar to the uterine lining grows outside the uterus, causing severe pain, heavy bleeding, and fertility issues.

Interstitial Cystitis / Bladder Pain Syndrome

A chronic condition causing bladder pressure, pelvic pain, and frequent, urgent urination without infection.

Small Fiber Neuropathy

Damage to the small nerve fibers that transmit pain and temperature sensations, causing burning pain, tingling, and numbness.

Invisible Illness

Irritable Bowel Syndrome (IBS)

A common disorder causing abdominal pain, bloating, and changes in bowel habits without visible damage to the digestive tract.

Dysautonomia

An umbrella term for conditions caused by dysfunction of the autonomic nervous system, which controls involuntary bodily functions.

Invisible Illness

Long COVID

A post-viral condition causing persistent symptoms — fatigue, brain fog, pain, and autonomic dysfunction — following COVID-19 infection.

Lupus (Systemic Lupus Erythematosus)

An autoimmune disease where the immune system attacks its own tissues, causing inflammation, pain, and damage to multiple organs.

Rheumatoid Arthritis

An autoimmune disease where the immune system attacks the joints, causing pain, swelling, stiffness, and potential joint damage.

Sjögren's Syndrome

An autoimmune disease that attacks the moisture-producing glands, causing dry eyes, dry mouth, fatigue, and joint pain.

Gastroparesis

A condition where the stomach empties too slowly, causing nausea, vomiting, bloating, and pain, due to nerve and muscle dysfunction.

Vulvodynia

Chronic pain or discomfort around the opening of the vagina, without an identifiable cause, lasting three months or more.

Trigeminal Neuralgia

A chronic pain condition causing sudden, severe, shock-like or burning pain along the trigeminal nerve in the face.

Amplified Musculoskeletal Pain Syndrome (AMPS)

A condition in which the nervous system amplifies pain signals, causing intense, disproportionate pain — often in children and teens.

Complex Regional Pain Syndrome (CRPS)

A chronic pain condition that typically affects a limb after an injury, causing severe, persistent pain and sensory changes.

Fibromyalgia

A condition characterized by widespread chronic pain, fatigue, sleep problems, and cognitive difficulties.

Connective Tissue

Ehlers-Danlos Syndrome (EDS)

A group of inherited conditions affecting connective tissue, causing joint hypermobility, skin that stretches easily, and chronic pain.

Postural Orthostatic Tachycardia Syndrome (POTS)

A condition where standing up causes a rapid heart rate and other symptoms, due to autonomic nervous system dysfunction.
