Friday I noticed a lump on the side of my neck. Not painful, so I waited 'til today to see my doctor. Prior to my visit today I developed welt-like bumps also on my neck. I also have developed many more lumps on my head. The doctor today believes they are swollen lymph nodes. The rash she had no explanation of - especially when I answered no to her question of poison ivy. Blood test today was completely normal (white cell count). I now find out that my boyfriend has poison ivy - just developed today - from the golf course he believes. My question is that if this is poison ivy, and I have never had it before, is it possible that all these lumps are indeed swollen lymph nodes reacting to the poison ivy? My concern is that they are very painful - although the rash is not itchy. I have not taken any other-the-counter medicines, although was given a topical cream for the rash - Mupirocin Cream USP, 2%. Is there cause for concern because of the many lumps (lymph nodes?) that are swollen and are painful?
