I have had nasal congestion for several days and now it almost feels like it could be an infection but I ve also got pain in the back of my neck at the base of the skull. I thought unrelated and tried stretching excercises but it has gotten worse progressively worse not better accompanied by an increasing headache as well all day. I have been treated with antibiotics twice in the past 6 mo for tooth abyss and sinus infection with cough. I m also on enbrel. Worried this could be another maybe more serious issue now that is already involving my neck.
