Hi. I Have Been Going Thru These Symptoms For A

Hi. I have been going thru these symptoms for a while now. At first I thought I was having a heart attack but I have been to the ER countless tones and EKG and blood work come back fine. But I feel this tight pressure in my head that occasionally makes me feel like all wavy also pain in my chest. Im not sure what is wrong but I know how I'm feeling isn't normal please help.
