Hi I am inquiring on behalf of my brother, who was camping just after Thanksgiving in the woods of central Pennsylvania. He was barefoot for a few moments, got his sock covered feet soaked in dirty brown ground water. He was in an area of high wildlife traffic. He was awakened by a sudden, sharp pain in his toe, and said it felt like being stuck with a hot needle. He thought it was a spider bite. Now, the toe is rotting and exuding copious amounts of puss. (ruined two pairs of shoes) Two doctors have tried and failed at diagnosing, and I suspect a parasitic infection. I want to show you a picture.(?)
