Glad your Xrays are good.....take it from me when the neck is fused even though xrays look good (which is great) there are many symptoms we can experience. The fusion causes a locked area in the neck so now all the other vertebrae from top to bottom take the stress of the immobile part trying to compensate and move correctly (which they can't). This info comes from the best of the best Neurologist,Neurosurgeons and PM Dr.s. It just is, so if we move, bend, reach, sit, sleep,turn or whatever incorrectly or work for BOSSES who lack empathy, we get a reaction, never truly knowing what we actually did. Symptoms of burning, spasm, weakness can occur.....whats the solution?????......you have to learn a new respect for your body and chores that you do...wish I could say you didn't but you MUST!
As far as your Marriage Counseling, go there knowing no one is wrong, a wise couselor told us once get back to your Why's, why you fell in love, why you married him/her, why you chose him/her to have children with. If your Why's don't matter anymore or you don't care to find them again, then it probably isn't going to work.
Good luck today and know we are all rooting for a positive,healing for both of you!
