hi I'm a 25 year old female and I have a question about lymph nodes. A little overlay I have had a swollen lymph node on the right side under the jaw closest to the ear for almost 5 years that I've noticed. About 6 years ago I had strep throat for about 6 weeks before a doctor finally gave me antibiotics. Every year since then I get it about 1 a year. It feel about 1.5 cm, rubery and doesn't move only sinks inside I guess you could say. I realise that there are 3 skin layers over it so I might be making myself go crazy for nothing. I've had numerous test done for other things like chest, sternum,and lung x-rays, more blood work then id like to count and everything seems fine other then scared tissue on lungs. A slightly elevated white blood cell count only when on antibiotic or taking inflamatory medication if that helps any. Other then those time everything is normal. And I also have many allergies and aortic valve regurgitation and wisdom teeth coming for 3 years now. Heart has been this way since I was born get checked every 2 year everything is always fine. Wisdom theeth don't need to be removed as per dentist and all in all I'm wondering if a swollen lymph node can stay swollen after so much trama to it, or should I get it checked again. It get even more swollen when I'm sick.
