No vomiting yet. Just feel like it may happen. No alcohol. Never had heartburn so I don't know what it feels like. Breath is fine. No back pain. It's more in the middle of body than the left or right. Only medication I'm taking is birth control. Been suffering since about midnight last night. No diarrhea. No fever.
Hello,Thanks for providing more information.
Well as you describe possible causes may include Gastroesophageal reflux disease, Gastritis, Gastroenteritis.
Now main concern is your consistent sharp pain inbetween chest and stomach which shouldn't be ignored.
And you should try OTC Liquid Gaviscon /Prilosec.
If pain is unbearable then visit ER for prompt management.
I hope this helps.If you have any further query then feel free to ask.Positive feedback and bonus are highly appreciated.Thank you.
