this fungus is a commensal organism, it lives with us,doesnt harm most of the time but just there, i really think you get it from exposure to athletes foot
. get some over the counter cream for athletes foot
, clotrimazole. it should take care of it. 84 days, thats 12 weeks, when i tested at 12 weeks, i thought it was to short of time, its not, 6 weeks is very reliable, 8 weeks is pretty conclusive, and 12 weeks and above, well your just following cdc and tx dept health standards.
