Hi all, Just want to know what are the common signs of herpetic whitlow and how it looks like before outbreaking. I have cold sores and have been pretty watchful and careful how I handle my mouth area. I've been washing my toothbrush every time I use it and that involves rubbing the soap into my hands to the point I have enough soap foam then I proceed to brush the bristles with it with my thumb. Lately my left thumb is having a weird tingling sensation and I'm worried that I might have possibly self infected my thumb. Although highly unlikely because I have not cuts and the skin seems pretty firm. And from what I have been told self infections is harder to get after the primary outbreak unless you deliberately make an open wound and let herpes fluid seep into the wound. So am I overreacting? Or could this be something totally different?
