I have had swollen lymph nodes in my neck for a few months. It started weeks back with a series of very painful migraines. Along with a bad tooth pain on a tooth which has a cavity and it bad condition. The tooth pain and migraines have all together stopped since then but I now have a constant feeling of disorientation and lack of balance. I feel very mentally aware but I can t seem to get my eyes to catch up to my brain so to speak. And my lymph nodes are still swollen and have allergic like symptoms even though I ve never had problems with allergies. And I am now struggling with constant stiffness and discomfort in my back and neck and feel like it s all related. I am only 25 but I do smoke as well. The constant disorientation is by far the most terrifying part of it all. And don t know what action to take next or the severity of the problem.
