I have headache, tight throat, chest pain, blur vision and very tired. Issit becos of my bad acid reflux, feel like someone is chocking me.

Acid reflux. Hello. Some of your symptoms sound like reflux induced but some don't. Choking sensation, tightness in your throat, and maybe even chest burning could be linked. The headache, blurred vision, and fatigue i'm not too sure about. Begin a low acid diet, and see your doctor for a complete evaluation. I hope this helps.
