Hello! I've mentioned before that my lymph nodes tend to wax and wane a bit in size - Over the past few days, I've had an inguinal (groin area) lymph node that seems to have gotten bigger and is a bit hard to the touch...this is all quite sudden. Is this something I should be (immediately) worried about? I feel fine and am experiencing no discomfort. I'm still new to my diagnosis and never sure when I need to call my doctor!
