That's a really low grade fever. The lymph node is normal to have after 6 infections in 2 months and you'll have it for a while. I would not worry about the lymph node as you've seen a doctor I presume at this point for the 6 infections. Did you take antibiotics? What types of infections did you have? Our lymphatic system is often misunderstood. People worry when they have a lymph node that is swollen but that is a sign that your lymphatic system was working. It's your body's defense and if you've had recent infections, that lymph node says "I'm aware and ready to fight!". They don't go away immediately. So, you've been checked and they say all is good. Do you have an issue with anxiety by the way? Even with doctor reassurance you have worried a lot. I've read several of your posts. Maybe talking about your anxiety with a doctor would help you overall? Something to think about. good luck
