Help! So much anxiety and not sure what else to have them test for. I have had so many blood tests. CBC, saturation, etc. I still can't get past this. I have a swollen lymph node in my groin. Doc said if it was the C word, it would have shown up in my blood, most likely. Also, I am waking up a little bit sweaty and not sure if it is considered a night sweat. It is under my boobs and a bit on my neck. Nothing is soaked, just damp. Anyone know if this is a night sweat? I am getting an ultrasound today, but scared. Do blood test rule things out?
