What cause bumps and enlarged lymphnodes in the back of neck started 3 days ago and what's the treatment . thx

You need to see your: Internist. Don't delay any longer. There are a few concerns. Lumps and bumps - i feel should always be looked at by a doctor. They often can be mistaken by a patient for something that they are not. I am surprised "mrs success" would actually wait 3 days before first asking for treatment. ...Your internist should be able to help. Good luck.
