Last week, you "have had HSV2 for 5 years". Now it's 4 months?
Sorry 5 years typing and not thinking
Wow... you and your issues with touching things....
Your HSV2 would almost certainly not be transmitted to another part of your body in the way you are describing - even considering the open wound.
Even taking the fluid off the blister and digging it into my skin?
Hsv2 is a sexually transmitted virus not by what your describing. Any issues with hand herpes would be with hsv1 not hsv2.
