Sounds familiar. All went away with treatment. I used herbs to treat and I am not exactly sure which ONE did it. I think it was a synergy thing where they finally were working together. Japanese Knotweed definitely showed me improvement within just a few days of taking it. I knew it was working.
What treatment are you on?
My neck stuff seemed to be my lymph nodes. I did Red Root for those but then one day my lymph nodes near my clavicle were swollen and I did the lymph node massage that is on you tube. Oh boy did I get them unswollen and I felt funny. I think I overdid it. The video said to do it 50 times and I do not recommend doing that, but it sure works if done in moderation and working up to 50 times.
