Final answer:
The likely diagnosis for the patient's symptoms is malignant hypertension, and the treatment involves immediate hospitalization and the use of anti-hypertensive medications.
Step-by-step explanation:
The patient presents with bilateral papilla edema, severe hypertension, and a history of Raynaud's phenomenon and GERD. Based on these symptoms, the likely diagnosis is malignant hypertension. Malignant hypertension is a severe form of high blood pressure characterized by rapidly increasing and severely elevated blood pressure.
