Re: has anyone ever had a blister that didnt hurt?
As i'm not a doctor, i'm just guessing ok, but people can have little bumps surrounding the nipple and a lot of these bumps contain something which supposedly is supposed to keep the skin in that area moisturised.
Is there a reason why you think you would have herpes? Possibly it could be a skin condition, something like eczma or psoriasis or some such condition. For a lot of these skin types of conditions it can be through a lack of omega 3 and 6 in the diet, which is what you get from eg: olive oil, flaxseed oil, avocadoes, fish etc.
Once again, i'm no expert and it's best to see a doctor and get any forms of sores swabbed so that they can get a lab analysis on what it is or isn't.
