Hi Lotus point,
Thanks for posting your question. I'm not a doctor, so I cannot give medical advice, but I have, and am knowledgeable about, herpes.
From what you describe, I don't see how your son's friend could have given you herpes. The only way for someone with oral herpes to give it to you would be if you shared food or drinks, or kissed or had oral sex. It doesn't sound like that is the case. Also, if you were to get herpes from him, it would probably only be in your mouth. Skin herpes can happen, but it's pretty rare.
It sounds like you may have a flea problem in your house, as I've never heard of herpes to cover the entire body in bumps. I would advise you to see a doctor immediately. He/She will probably be able to look at you and make a diagnosis pretty quickly. If you're in doubt, you could check out the Herpes Symptoms page to see if those symptoms match yours. You may also be interested in the Herpes Prevention page.
If it does end up being herpes, feel free to come back and ask more follow-up questions. Otherwise, good luck and take care!
