Confused

Shaylia

This has never happened to me before so I’m really confused? Okay so I always eat pickles no matter what I love pickles yesterday I ate some and I got a heartburn and I’ve never had a heartburn a day in my life. Then today I go a headache and started throwing up water like but I didn’t throw up a lot just a little but multiple times during the day. Can anyone give me answers I’m scared?
