### input:
My symptoms started about a year ago, i was woken up suddenly in the middle of the night, it all happened so quick i jumped straight up and fell to the ground as my left leg and arm were numb and in pain, then feeling slowly came back. After this mild neck pain and stiffness started and which over the last year has progressed to severe and seems to be traveling down into the top of my back. I have constant headaches and eyeball pain as well as muscular pain in arms and legs and general fatigue . Recently my numbness sensations have started to happen more frequently again awakening suddenly during the night with one side numb and in pain and causing me to fall, sometimes i just awaken with just my arms numb. I had MRI of BRAIN AND CERVICAL SPINE in March 2012 both were clear. At time of scans i had very MILD neck pain/stiffness and only 1 episode of numbness. Since then they are becoming more and more frequent and my doctor has now diagnosed me with anxiety. Can you still have ms with an all clear mri scan? I do believe i have some anxiety but can this not also be a symptom of MS? Everything i have read, forum after forum its quite clear that doctors miss-diagnose ms all the time and that it is a very hard disease to diagnose. I am also getting physical therapy for the neck with no real affect, and when my pyhsio performed a reflex reactions exam there was no reaction to my left arm, when i told the doctor he completely ignored it. I am 25 year old male non smoker who has went from attending the gym twice a week, playing for an amateur football team and golfing regularly to basically sitting in front of the TV and not wanting to do anything.

Hi, welcome to Chat Doctor.  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.  Regards.
