I Am Pretty In Touch With My Body. 8 Days

I am pretty in touch with my body. 8 days ago I got a very bad stomach virus. I vomited for a long time. At one point during this I felt like the bottom back of my head ripped. since that time I've had severe pain BUT prior to that had daily headaches. Saw my PCP who gave me Migraine meds and Flonase. I am worse. My left eye swells off and on and it hurts to touch the left side of my face and head. Antihistamines have helped the allergy/sinus issue.
