Hi, welcome to HCM.
Fortunately you are not suffering from multiple sclerosis
. It affects functions very severely. There nothing like a numbness
in only one arm or leg. So please forget about MS. Also for diagnosis there should be combined features of clinical and radiological features.
I think your doctor is correct. You are having anxiety
related disorder. Just take a second opinion
of cervical spine
imaging. Otherwise you need to consult for anxiety.
Hope I have answered your query.
