What Causes Migraine Headache Followed By Dizziness And Shortness Of Breath?

I am experiencing a weird combination of symptoms right now that I have never had. I went to take what I had been planning on just a short nap within a few hours of waking up due to having one of the worst migraines I have ever experienced. I ended up sleeping for several hours. When I woke up, the headache was a great deal less, so I decided to take the dog for a short walk to the gas station. While in the store I had a short wave of dizziness but felt fine within a minute or so. About 2 blocks into my 4 block return home, I started having a hard time breathing. It felt as if I could not expel the used air from my lungs all the way and that I was able to pull in less and less air with each breath. I made it home, forced myself to drink a few cups of water and sat down. I started feeling extremely weak. The headache returned with triple the force before I had laid down. I could barely hold my head up, lifting my arms was nearly impossible and my legs felt like the muscles were spasming to the beat of my pulse. My neck felt like it was swelling, stiffening to stone and as if it were breaking at the base of my head. The dog was looking at me and crying at me, still has not left my side. As I am laying down, I keep hearing sounds that I know are not there and I have caught myself answering a couple questions that no one had asked and that I cannot remember even thinking about. This is not normal behavior for me. Although I have not been able to keep solid food down for at least 5 days, I have been making sure I have been calories and nutrients using liquid options. As of this moment, I still have a nasty headache and I m sweating in my apartment that reads 60° and my skin feels cold to me. The hospital in town does nothing when I go in there and the get me out the door as quickly as they can when they realize I don t have insurance.
