5w3d. Severe headache and what feels like heartburn

Heather
So it started yesterday. Headache and has gotten worse and chest pain that feels like heartburn. I barely slept last night. Felt like my heart was racing. I get migraines as it is. And I do take Prevacid for heartburn etc.  
But this is awful. Anyone else ?? It's like I get winded just doing little things. My head is throbbing.
