You didn't specify who to go and see (if they really had to see someone about it a pharmacist would be more appropriate, but again this would be a waste of time as they'll sag what's already been said), and you put 'will' in bold to scare tge OP into thinking it's more serious than it actually is. I see you completely ignored my point stating there's a reason why information is released to the public about treating minor cuts and grazes themselves at home without medical intervention.
Yes you can post where you want, but you're not doing yourself any favours by going into overdrive about a small cut and worrying the OP who has already stated they have health anxiety.
