I have had swollen lymph nodes under my chin for a couple of weeks. other symptoms I'm experiencing include; shortness of breath, soar throat, pressure in my neck and head. I have acide reflux and a hiatal hernia. chest xray is normal. I've recently had and endoscopy and that's how i found out about Hiatal hernia. I'm concerned about the swollen nodes. Also, complete blood work up was done and everyhting is normal, except mu TSH level was 5.9....
