Having whitlow on both hands is not going to happen. I would find out what test they gave you and the numeric value of the test. Meaning wss it an igg or igm bloodtest and what exactly was the elevated number.
Have the bumps on your hand tested for HSV.
Impetigo is a highly contagious skin infection where sores are on the lip area. Herpes is an infection that lives in the nerve area and can surface from time to time. Over 50% of the adult population has hsv1. Most get it as a child.
I highly doubt you spread it to your hands. Whitlow which is herpes of tbe hand ir finger is almost always extremely painful. It's also rare.
A little of my life history. I have only been sexual active with 3 men my whole life. And have been with my last bf for 3 years. Have never had a cold sore or anything to think I had a cold sore.
