cold sores
"I started getting fever blister in my late 20's when I was on chemotherapy. They were usually in my nose and I just suffered through. I few years ago I had a huge cold sore on my lip that caused my lip to literally swell to my nose. I went to the doctor and started on Valtrex, absolutely amazing I never get them anymore. It was to late for this horrible episode but now when I feel an out break I start the tablets 2,000mg 2x day. I have recently started feeling a lot of tingling and itching and numbness across the nerve path after is take the medication. I tell my husband it is like the drug is fighting the virus on the nerve has anyone else experienced this weird side effect?"
