severe neck pain with cold sore outbreak

i thought it was a coincidence and maybe it is but i have the worst neck pain and can barely move my head.  i thought i had just slept on it wrong but it is gradually getting worse.  after thinking about it i realised it started a couple of days before the cold sores showed up.  just wondering if this is common.  i have only been diagnosed with cold sores for a year now.  i never had them before last year but unfortunately my husband had them most of his life and gave them to me.  just really concerned about the neck pain.  any help would be appreciated.  thanks

Hello and hope you are doing well.
The cold sores and the neck pain may be unrelated. Muscle strain can cause neck pain. Sometimes problems in the cervical (neck) spinal cord like a herniated disc or something going on in the right side of the brain could be possible causes. For symptoms such as these consult your family doctor and have them check you out. He may then refer you to a neurologist for an objective assessment of the weakness. An MRI of the spinal cord and brain may also help to arrive at a diagnosis.  
Hope this helped and do keep us posted.
