However, if you feel things are OK with
your job, may be best left alone and not cause any added problems. I can tell you
your employer probably has shades of doubts, even if they remain unspoken, so you'll have to decide.
Errors do happen. Still, the patch you used wasn't prescribed, so that would be seen in my eyes as an employer as drug abuse, so always be careful what you use even if it's for pain.
