Re: Does this sound possible with test results. Ct-scan?
DId your Doctor have a plan for the cyst? I have heard of cysts causing structural alteration in your sinuses before, but the only long term lymph node aggrevation triggers I have experience with are long term sinus infections and mono. My lymph nodes have been swollen with persistant sinus infections for periods up to 3 months with out relief... and if I got another infection shortly after they would flair up again. When my fiance/husband gave me mono I had about a six month period of aggrevated... swollen lymph nodes in my neck, under my arms, behind my ears, on the back of my neck, and allon my upper spine.
As to the cyst, my sister-in-law had one and it was removed as soon as it was discovered. She was feeling so good that she doubled her productivity instantly and actually felt relief from chronic sinus headaches as well.
Best wishes on solving your problem.
