over the past week, I have had left sided neck tenderness, I feel some tightness and it is sore, like if you slept wrong. Getting more discomfort. and I also noticed my ear on the left side is hot and bright red. I DID have a pretty good fall, about two weeks ago and hit my head, but didn t think I hurt anything. Not sure if this is related, However, I am Worried it is Lymph nodes. I am a smoker of many years, and also take weekly injections of Humera for Arthritis.
