Brief Answer:
Stomach flu likely, needs symptomatic remedy

Detailed Answer:
Thank you for asking

I read your question and i understand your concern. Pressure in chest with vomiting and stomach pain indicates gastric discomfort likely dyspepsia or gastritis likely viral gastroenteritis also called stomach flu.

Take some antacids and some gastric motility enhancement medications and continue home remedies like garlic, plenty of fluids and electrolytes etc. DOnt use advil or tylenol any more it will worsen the symptoms. Suck on peppermint candy, or chew a stick of peppermint gum. Peppermint may relax tight muscles in your stomach and help decrease the stomach contractions that may be causing your nausea.

-Rest in bed until you are feeling better.
-Sip a rehydration drink to restore lost fluids and nutrients.
-After vomiting has stopped for 1 hour, drink 1 fl oz (30 mL) of a clear liquid every -20 minutes for 1 hour. Clear liquids include apple or grape juice mixed to half strength with water, rehydration drinks, weak tea with sugar, clear broth, and gelatin dessert.
-Avoid orange juice, grapefruit juice, tomato juice, and lemonade.
- Avoid apple and grape juice if you also have diarrhea.
- Do not drink milk products, alcohol, or carbonated drinks such as sodas.
-If you do not have any more vomiting, increase the amount of fluid you drink to 8 fl oz (240 mL) during the second hour. If you are not vomiting after the second hour, make sure that you continue to drink enough to prevent dehydration.

When you are feeling better, begin eating clear soups, mild foods, and liquids until all symptoms are gone for 12 to 48 hours. Gelatin dessert, dry toast, crackers, and cooked cereal are good choices. Try to stay away from strong food odors, which can make nausea worse.

The acid in vomit can erode dental enamel and cause tooth decay (cavities). Rinse your mouth with water after you vomit. Brush your teeth if you can.

if the vomiting persists or fever shows up or the chest pain exacerbates rush to ER for further management.

I hope it helps. Take good care of yourself and dont forget to close the discussion please.
