I am recently diagnosed with herpes on my right arm and shoulder around 10 days. I came to know know this about one week later. It happened to me first time. It started with tingling in right arm and itching and a small blister on upper shoulder. Tingling goes automatically within three days approximately but itching still persists and blister is healing. Started medicine after a week when came to know. So, now my question is for my son, he is just six and a half months. Can he get infected, if he is already how can I check that. And what precautions I need to take for future.
