Tingling In Right Side Of Head, Hot Flashes In Face And Right Ear, Nausea, Pain In Right Ribs With Headache. History Of AVM On Right Side Of Brain In Childhood. Connection?

I have been having these symptoms for over a year now. It usually starts by having chills or a tingling sensation on right side of my head, and then usually the right side of my face feels hot including my ear. I get nauseous, I go to the restroom and go to the sink but when I gag nothing comes out. I have been getting sharp pains in the right side under my ribs out of nowhere. There was this only one occasion that I had blood in my stool. After I have these “Headaches” my head just feels like it’s bruised or swore, it’s a weird sensation that I really cannot explain. They come like the rhythm of a heartbeat. I have tried Tylenol for many times but it’s a disappointment, it usually does not work so I try to sleep it away.
When I was at the age of 6 I had a Brain AVM (arteriovenous malformation) on the right side of my brain. Last month on the 11th I went to the doctors and had a UTI (urinary tract infection).
What I’m trying to find out, if these “headaches” are normal I guess for a person like me who had an AVM, or is there something I should be worried about.
