Hi, and thanks for your query on eHealth forum!
Heated body and change in eye color could be due to high blood pressure or hyperthyroidism (increased thyroid function) or if this has been recent onset, conditions causing jaundice need to be ruled out. Vit D, B12 and iron and testosterone deficiency should be looked into too. Most of these conditions also affect your memory.
Please consult your healthcare provider for further guidance as you will need some tests and blood pressure measurement etc for a confirmed diagnosis.
