So, yesterday while bathing, i found out there's a pea sized lump/lymph node infront of my right ear/tragus. It's firm but movable, yesterday it was not tender, maybe i palpated it more so it feels a little tender now. Does this mean i have any infection? I am suffering from insomnia since a month without any cause. All bloodwork is normal, including cbc, lft, kft, sugar, thyroid. Ultrasound full abdomen is normal as well. I had a viral in 1st week of January. Since then m having such issues. Please help me. Is this anything serious?
