After eating something i immediately vomited and now it feels like there's a soreness/straining pain that comes and goes in my throat. i don't have any allergies but are there any ways you'd suggest soothing or calming this response?

Reflux/pregnancy?: Is there a chance that you may be pregnant? If so , get tested. This may also be from reflux but it is not that common in your age. If this has been present for less than 3 days, perhaps you can wait. If this has persisted for more than that or been getting more severe, it is best to see your doctor. In the meanwhile, try some OTC acid controller or suppressor and see it it helps.
