Differential Diagnosis
- Single Most Likely Diagnosis
- Fibromyalgia: The patient's symptoms of chronic fatigue, widespread pain, tender points, and brain fog are consistent with fibromyalgia. The presence of irritable bowel symptoms, headaches, and sensitivity to temperature changes also support this diagnosis.
- Other Likely Diagnoses
- Systemic Lupus Erythematosus (SLE): The patient's family history of lupus, increasing ANA score, and symptoms such as joint pain, skin rashes, and photosensitivity suggest SLE as a possible diagnosis.
- Ehlers-Danlos Syndrome: The patient's symptoms of easy bruising, poor wound healing, and joint hypermobility (suggested by scoliosis in her mother) may indicate Ehlers-Danlos Syndrome.
- Narcolepsy: The patient's symptoms of excessive daytime sleepiness, sleep paralysis, and REM sleep disorder are consistent with narcolepsy, especially given her family history.
- Irritable Bowel Syndrome (IBS): The patient's symptoms of loose stools, abdominal pain, and cramping are consistent with IBS.
- Do Not Miss Diagnoses
- Multiple Sclerosis: The patient's symptoms of numbness, tingling, and decreased coordination could be indicative of multiple sclerosis, which would require prompt diagnosis and treatment.
- Thyroid Disorder: The patient's symptoms of fatigue, heat intolerance, and cold intolerance could be indicative of a thyroid disorder, such as hypothyroidism or hyperthyroidism.
- Vasculitis: The patient's symptoms of skin rashes, joint pain, and easy bruising could be indicative of vasculitis, which would require prompt diagnosis and treatment.
- Rare Diagnoses
- Mast Cell Activation Syndrome: The patient's symptoms of skin rashes, flushing, and gastrointestinal symptoms could be indicative of mast cell activation syndrome.
- Porphyria: The patient's symptoms of abdominal pain, neurological symptoms, and sensitivity to sunlight could be indicative of porphyria.
- Autoimmune Autonomic Ganglionopathy: The patient's symptoms of orthostatic intolerance, heat intolerance, and gastrointestinal symptoms could be indicative of autoimmune autonomic ganglionopathy.
