My athlete's foot symptoms have returned, should I consult a doctor again?

If your athlete's foot symptoms have returned despite undergoing treatment for four weeks, it is important to investigate if there might be a source of recontamination. Make sure to check if you walk barefoot in certain areas or if surfaces like bathroom mats have been properly cleaned. If the issue persists even after addressing potential sources of contamination, it would be wise to consult a healthcare professional to explore other possible causes.
