Hi, I was breaking up branches in my yard when I later noticed my index finger had swollen. First thing I thought was something bit me or a branch stuck in my finger. I went to the emergency room, they took an ex-ray and said it was Herpes Whitlow. When I came home I looked it up on-line and my finger does not look like that at all. I have no rash, no blisters, no rash at all. it was just swollen and now the swelling is gone. They gave me Acyclovir 400 MG to take. My question is, if this was misdiagnosed and if all I had was just a bug bit and I take this medicine, could this medicine harm me in any way?
