Fungal nail infection sufferers may wish to ask for chemical treatments through international healthcare policies.
Lamisil and Daktarin were highlighted as two possible solutions by Society of Chiropodists and Podiatrists spokesman Matthew Fitzpatrick, who noted these items can be bought from the majority of pharmacists and supermarkets.
People who have "really bad" cases of fungal nail infection could ask for Terbinafine, which is an oral version of Lamisil.
This drug is "not given lightly", the specialist declared, pointing out it is not recommended for people with liver problems.
He said the condition can be avoided by maintaining feet in such a way as to make them inhospitable for fungus, such as by allowing shoes to dry out while thoroughly cleaning between the toes.
"Never wear the same pair of shoes two days running," Mr Fitzpatrick asserted.
According to the British Medical Journal, many people suffer from this condition, which is not usually serious, although it does not look pleasant.
Symptoms include crumbly white nails, while the infection can eventually make it painful to walk.
