Hi Renee, and summer girl too..
Gosh, most of your symptoms sound like what I experience also. A couple of years ago I started feeling as if I was veering to the left when walking, my neck was super stiff and painful, I started having ocular migraines and blurry vision. My left side seemed slightly weaker than the right and I was having lots of tingling everywhere, there were other odd symptoms too. I had CT scan, MRI and bloodwork, even a lupus test. All came back ok. Doc put it down to anxiety. I was so shocked that these symptoms could be anxiety related, they were so physical that I just couldn't believe it. I developed a degree of health anxiety which I am still battling. Like you, my symptoms would come and go.
You asked if symptoms eventually disappear. Good news, I believe they do. I am still experiencing migraines and vision disturbance and a bit of dizziness, but the veering to the left sensation and the tingling and the arm weakness is gone, and hopefully wont come back! Interesting that since I have been taking steps to heal and help myself, some of the symptoms have gone away. I am still trying to convince myself to go on AD's, but I have make adjustments to my diet, sleep, and am starting an online CBT course and slowly I seem to be having less symptoms. Like Summer girl said, once you address symptoms they can dissipate In the past I had panic after eating food, it lasted for years and has now totally gone. There were a number of months where I was waking up with a panic attack at exactly 4am every morning, eventually that settled too. I have many other example of symptoms that have hung around for months then disappeared, Its so strange how anxiety manifests.
I hope this gives you a bit of hope that your sensations are 'normal' for someone experiencing anxiety. Best of luck and I hope your symptoms disappear soon.
