Hi jillgirl
Within a couple of days of my first set of injections, I got a cold sore. I hadn't had one in years, so I knew it was related. It just seemed like I was the only one with this reaction.
Mine actually wasn't very bad, because I use a European lysine cream that helps if you put it on as soon as you feel the tingling. I also take collagen peptides everyday--they include lysine. Last week, I had my second set of injections, and, thankfully, so far, no cold sores.
Have you only had the first injections so far? Let's hope our outbreaks were a one-off.
