About three years ago I got ate up from my ankles up to my calves and it was bad...I couldn't count how many bites there were. I tried everything you could think of including the nail polish, benadryl, spray on meds, bleach...NOTHING worked, no difference at all...it was horrible and finally after about a week of misery the itching finally eased up. All I can say is good luck...I feel your pain so to speak.
