A member asked:

Read that cold sores are caused by hsv 1 and 2. can the virus travel up nerves and cause outbreaks on feet, ankles, arms, or cause loss of hearing? can it cause liver problems?

Locality based pbs: These viruses do hibernate between outbreaks within the nerve roots where they are found. (facial nerve roots) They do not travel around the body. A cousin of HSV that causes chickenpox can emerge in other body sites as a shingles outbreak which is similar in function to the cold sore process but the two issues are not the same. They do not infect the liver.

Other causes : Similar blisters can occur on foot, ankle and arm can be caused by the drug furosemide which can also affect hearing, can cause liver function abnormality by loosing high electrolyte. Cold sores may be related or not. Allergic reaction can also give similar symptoms.
