Hello! Thank you for asking on HCM! Regarding your concern, your symptoms may be related to inflammation (like temporal arteritis) or infection. Have you measured your body temperature during these days? I recommend consulting with the GP for a careful physical examination and some lab tests : - a complete blood count for infection - inflammation tests (fibrinogen, PCR, sedimentation rate) - fasting glucose - blood electrolytes. A brain CT scan may be necessary to exclude possible intracranial lesions, if suspicions are raised after the above tests. Hope to have been helpful! Best wishes, Dr. Aida
