i need help!!!! my friend went swimming at wekiva springs in florida, he got out of the water, was itching all over. he woke up the next day covered head to toe in a severe rash. i took him to emergency room almost 2 weeks later, hes gone to a clinic, hes tried every cream, benadryl, everything. it has been over a month he has had this severe rash, what could be causing this and how can he treat it? is it an allergy from something in the water at wekiva springs? and he has no health insurance to go to a dermatologist, PLEASE HELP ME, hes so depressed and embarrassed he won't leave his house!
