Hello
You are having
nausea , vomited , profusely sweating , these symptoms disappeared at once , and again returned.
Now
vomiting again.
The exact cause may be hyper acidity or
gastritis or over eating or spiced food .
You didn't mention your age , sex , diet which you taken just 2-3 hours before these symptoms .
If you are taking any medicine or not ?
In such condition I advise my patient to taken ondansetrone 4 mg mouth dissolving tablet ( keep one tablet on the tongue , it will melt within 2-3 minutes ) .
After say 1/2 hours take
antacid ( if it contains oxetacaine , better) .
Nausea will stop instantly .
If no relief then consult a physician and get his opinion.
Such nausea may be due to gastritis , hyper acidity , over eating , improper sleep .
So deal as mentioned above.
