Sorry to hear about your husband's ordeal!! My husband contracted this on our honeymoon trip to Beaches Inn. We had alot of rain that week and figured he must have stepped in something in the damp sand. Doctor figured that the access point was probably some athlete's foot on my husband's foot. Took several weeks of doctor's appts to figure out what was wrong...MD gave him antibiotics, prescription creams for athlete's foot and anything else he could think of. Nothing worked and he finally referred him to a specialist who took one look and knew instantly what it was. Had to have the medication sent from someplace in Ottawa....one pill and the worm was gone! What a resilient little creature....
