The National Poisons Information Centre of Ireland has issued a warning over the dangers of weever fish around the coast.
There have already been dozens of reports of stings from the dangerous tiny fish including a number in Donegal.
With the weather expected to get better in the coming days, more and more people will flock to the coastline.
The fish is found in all parts of the Irish coast but only in sandy areas, usually in warm shallow waters in the hour before and after low tide.
Unlike most fish, they have no swim bladder, meaning that they sink to the bottom as soon as the stop swimming.
They are, therefore, difficult to see because they spend most of their time buried under the sand. The have sharp spines containing venom on their dorsal fin.
Standing on a weever fish results in immediate intense, burning pain with the most intense pain coming in the first 2 hours and can result in swelling, numbness and warmth.
The NPIC has issued a list of guidelines for people to follow is they are stung by the tiny pest.
People should:
* Seek assistance from a lifeguard, if available.
* Submerge the affected limb or wound in hot water, as hot as can be tolerated for up to 90 minutes or until pain is easing.
* As the sting can result in numbness, immerse the unaffected limb too, as this may prevent inadvertent scalding.
* Cold applications may worsen the discomfort.
* Paracetamol can be considered to relieve pain. Care should be taken when pain relief is given that thermal burns do not occur due to the effects of the pain killer masking the temperature of the water used.
* The puncture site should be examined and embedded spines removed.
* Seek medical attention from a doctor as a tetanus and/or antibiotics may be required.
* Call the NPIC on 01 8092166 if you stand on a weever fish.
