Thank you for your query on Healthcare Magic.
The stomach upset
and the red spots with puffy eyes is looking like an food allergic reaction
Did you eat any new type of food or any fish variety.
For vomitings, you can take ondansetron
tablet in prescribed dose.
Oral antihistamines like cetrizine
will decease the itching.
I advise you to consult the doctor for physical examination and for the medication.
Hope I have answered your query.
