First and foremost, was the poison ingested or sprayed on your body. Pyrethroid poisoning mostly leads to neurological symptoms and body surface absorption is slow. Symptoms could be a result of organophosphate poisoning commonly found in a mixture with pyrethroid in bug sprays. The only confirmatory test is cholinesterase assay which can only be done at a hospital and takes time. The doctors must have assessed your condition and discharged you since no further management like respiratory support was necessary.The pain in your abdomen could be from the irritation of your stomach lining too if it was ingested.
