I have been sick for about a month now, uncontrollable coughing with headaches. A week ago a lump popped up on my neck but its not under my ears around my throat or anything like that, It is on the side of my neck, closer to the back. I finally went to the dr, (I havent been there in four years) He said I have Acute Bronchitis, I asked him about my knots on my neck and he said they were swollen lymp nodes, The only problem is he didnt look at them or touch them or anything. THere is no redness or tenderness, it is just a hard knot that appeared a week ago.My antibiotics are almost complete and the knot is not going down any. I also had blood in my urine that filled a whole napkin, It only happened the day the knot came up. I am really concerned- Do you think I have something to be worried about? Please give me some advice!
