Swollen lymph node in right armpit

😄😄😄 • You will keep in perfect peace, him whose mind is steadfast, because he trusts in You. Trust in the Lord forever, for the Lord, the Lord, is the Rock eternal. -Isaiah 26:3
Anyone else experienced this? My dr checked it and he didn't seem worried at all. It has gone down a little but it is still there. I had a bad upper respiratory infection a month ago and it showed up but hasn't completely went away 😟
