Differential Diagnosis for Crippling Multiple Joint Pain from Sun Exposure
- Single most likely diagnosis
- Lupus: This is a chronic autoimmune disease that can cause joint pain, skin rashes, and other symptoms. Sun exposure is a known trigger for lupus flares, which can lead to crippling joint pain.
- Other Likely diagnoses
- Psoriatic Arthritis: This condition is characterized by joint pain and skin psoriasis, which can be exacerbated by sun exposure. While not all cases are triggered by sun, it's a common enough association to consider.
- Rheumatoid Arthritis: Although not typically triggered by sun exposure, some patients with rheumatoid arthritis may experience worsening symptoms due to increased inflammation caused by sun-induced heat.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Sickle Cell Crisis: Sickle cell disease can cause joint pain, and dehydration from sun exposure can trigger a sickle cell crisis, which is a medical emergency.
- Porphyria: This group of rare genetic disorders can cause severe sun sensitivity, leading to blistering skin lesions and potentially crippling joint pain. Some forms of porphyria can be life-threatening if not promptly treated.
- Rare diagnoses
- Ehlers-Danlos Syndrome: This group of genetic disorders affects connective tissue and can cause joint hypermobility and pain. Some patients may experience worsening symptoms due to sun exposure, although this is not a primary characteristic of the condition.
- Solar Urticaria: A rare condition characterized by hives and joint pain triggered by sun exposure. While not typically crippling, it can cause significant discomfort and should be considered in patients with unexplained sun-induced joint pain.
