Hello!
Thank you for asking on HCM!
I read your question and understand your concern.
Her symptoms may be related to a gastro intestinal disorder (
esophagitis or esophageal spasms), or an
allergic reaction the drink.
I recommend bringing her to the ER as soon as possible and perform a careful physical examination, a resting ECG, a chest x ray.
An immediate treatment may be necessary in case of an allergic reaction.
Further blood lab tests like:
complete blood count, fasting sugar, blood electrolytes,
kidney and liver function tests and a GI
endoscopy may be necessary to establish the possible cause.
Hope to have been of help!
Best wishes,
Dr. Iliri
