I have sarcoidosis. Not in the lungs in my chest cavity. It s not unusual for my lymph behind my ears to swell occasionally. Well a few months ago I had a lymph in my groin swell a little. Like a little pea size ball. No pain nothing. All of the sudden a few days ago it became quite enlarged. Painfully so. It s right on my underwear line so any movement hurts. I just moved and my insurance doesn t kick in for a week and a half. Help!!! I m really scared and nervous. I work in a hospital in the icu so I m used to seeing the worst case scenerio. I know better but it really has me worried as the more I ignore it the worse it gets.
