Just goes to show you we are not all trained the same. I leave my site uncovered and get along wonderfully. I actually rub on the antibacterial foam soap and leave it there while I brush my teeth then gently rub with a wet washcloth to remove the soap residue then use a dry washcloth with some pressure to rub it dry and remove any scabs or crusts. I cannot use the tape on a regular basis as I get blisters. Good luck, hope the unit helps you get it healed and over being painful!
UPDATE ..thanks for all your help guys , had my site checked out and a swab taken, although they dont think its an infection (they think its trauma) i have got a course of anti-biotics and an antibiotic cleanser to use , just to be on the safe side ..phew , so glad thats sorted !
