About 8 weeks ago I found a enlarged lymph node on the side of my neck, I started googling this and it said to be concerned if I started getting night sweats. Sure enough after I read that I woke up one night to sweat between my breasts (I had a sweatshirt on and 2 blankets so I ruled it out as being warm) however now I sleep with the window open and fan on so I'm cold and ive still been waking up with sweat on my chest/in between my beasts. It's enough to make my shirt damp but not drenched and my chest is the only place this occurs. Are these considered night sweats? Is it anxiety? I work out everyday and I'm on birth control, both of which I heard can cause night sweats. But I still have the bump on my neck even though it has decreased some in size. Help?
