Feeling too cold frequently and then getting sweating since yesterday. Light abdominal pain.

Professional Assessment: The presenting symptoms of temperature dysregulation (cold sensation followed by sweating) combined with abdominal pain raises several differential diagnoses including infectious processes (viral/bacterial infection, early sepsis), endocrine disorders (thyroid dysfunction, adrenal insufficiency), or inflammatory conditions (early appendicitis, diverticulitis). The pathophysiological mechanism likely involves either inflammatory mediators affecting the hypothalamic temperature regulation center or endocrine dysfunction affecting metabolic rate and autonomic responses. For a 39-year-old male, key risk factors to consider include occupational exposures, recent travel, immunocompromised status, and family history of autoimmune or endocrine disorders. Additional testing indicated includes complete blood count, comprehensive metabolic panel, thyroid function tests, morning cortisol, blood cultures if febrile, and abdominal imaging (CT or ultrasound) depending on the progression and location of abdominal pain.

Take 400mg of Ibuprofen to address both the abdominal discomfort and potential fever symptoms, along with plenty of fluids (at least 2-3 liters of water daily) to prevent dehydration. Rest in a room with comfortable temperature (around 70°F/21°C) and wear layers that can be easily removed when sweating occurs. Apply a warm compress to the abdomen for 15-20 minutes every 2-3 hours to help alleviate the abdominal pain. For additional treatment recommendations, ask in the chat.
