Hi...I am at the same point post op as u almost 2 yrs...and I have had some pressure return, but it appears to be weather related at this point for me.....
But, urs could be scar tissue...when was ur last MRI?
Were u checked for a syrinx, tethered cord....?
U really should call ur dr and let him know about these changes u r having and get them checked.
I had my surgery Nov 2010 and I am having luck with migraine meds. The surgery has triggered a lot of migraine headaches. They are not the typical migraines that people describe. They start at the base of my neck and work up my head.
Feels like a lot pressure. So much it feels like my ears will pop! When I take a imitrex this will fade out.
For a long time I thought it was pressure.
Now I'm working on getting the muscles in my neck to relax as they trigger these headaches.
