I have gotten cold sores for approximately 7 years. They started spreading all over my lips - but the ones that were new were not tingling like they originally did and came without warning. I was taking so much aciclovir and valciver. Then... I got exceedingly itchy blisters on my fingers, followed by unbelievable swelling in that finger. The pain is intense and the itchiness – OMG! (Apple cider vinegar helped alleviate these side effects - Thanks to you on Earth Clinic) I had a bout of this on my fingers for 4 months. I could not use my hands. I thought it was herpes whitlow. What cleared it up was when I was on a diet of only rice with fried vegetables – no flavorings or soy sauce added. The problem cleared up in about 5 days! Both my fingers and lips. Simultaneously, I had a brain fog clear up and anxiety that had been thwarting me for about 2 years. I then found out I am completely unable to eat Gluten. I guess the rash thing is a form of Dermatitis Herpetiformis (NOT HERPES! ) which is a consequence of not being able to tolerate gluten. (I still got the original and authentic Herpes cold sore that tingles - but it comes much less often as I take Lysine daily and it seems to come less often now that my body is not fighting the "poison" that I was eating previously). Before I had that authentic cold sore almost every 2 weeks. I am also unable to have most additives to food, and food that is GMO or treated with pesticides. For the last 3 months I have been strictly eating only at and home and it has stayed clear. I eat 100% organic, gluten free and no longer eat packaged food.
