Hello all! I have been taking L-lysine a while for herpes simplex virus (HSV-2), as I don't want to go with acyclovir for too long (swapped two months ago). During this time, I have started having lots of problems with my joints. I have searched through all of Google Scholar, but I haven't got any insight on if l-lysine is bad for fibrosis or not. Has anyone here been using it or had side effects. All replies are welcome!
