I am suffering from Acid Reflux or might be from GERD. This happened due to Anxiety. I never felt heartburn. From three- five days I am feeling itching in my throat. Today I noticed tiny red spots in my throat. From yesterday, I am feeling pain on the left side of my neck (outside pain, not inside my food pipe) and little bit of Swelling . The pain only happens during Yawning, When I move my head upwards and when I am about to ly on the bed. Pains feel like Jaise mere neck ki skin khich rhi ho. I discovered small lump in my neck near to my Jaw. Today, i felt the same on right side. Is this happened because of acid reflux? Is this serious Matter? Please help me.
