About a month ago I noticed some sensitive lumps in my armpits. They didn't go away so I went to the doc and was put on antibiotics for a week and now I did blood work and go for a ultra sound next week. I've noticed more sensitive lumps appear lower in my armpits and also a lump raise on the right side of my neck. I also have one in my groin area on the right side. They aren't painful and probably would have noticed the lump in the groin had I not been checking for it but the one on my neck is visible. I know a lot has to happen in the next couple of weeks to find out whats going on but should I be worried? I'm 34 years old and in good health. The research I've been doing has my a little concerned. Any thoughts?
