Hello! I read carefully your question and understand your concern. There are some different disorders which may mimic this clinical scenario: 1. A temporal arteritis would explain the headache on the tempels with the protruding vein 2. A viral infection would cause all the other general signs. 3. A high blood pressure would explain headache and nose bleeding 4. Thyroid dysfunction 5. Anxiety. I would recommend you to consult with the neurologist for a careful physical examination for neurological signs, a routine blood test, renal and liver function tests and thyroid hormone levels. A brain CT scan may be necessary. Hope to have been helpful! Greetings! Dr. Aida
