Hi, I have been under investigation for a few years now and am still unsure exactly what is going on.
In 1990 I had radiation therapy in the neck area for hodgkins lymphoma. Shortly afterwards I was tested for MS as I had l’hermittes which is caused by inflammation of the cervical spinal cord. MRIs were clear as was a lumbar puncture and VEPs etc. I was told that the radiation had caused temporary inflammation and it will resolve. It did after several months.
15 years later I had numbness in my left arm. Had another clear MRI and was sent on my merry way. The numbness resolved after several weeks.told
Then 3 years later I had more numbness, fatigue weakness etc and it felt like an MS attack. My GP told me it must be a virus as the recent MRI was clear. After 8 weeks I was almost back to normal. Then a year later drop foot started to develop. In 2011 I saw a neurologist and a lesion was seen on the cervical cord.
I was told that when there had been inflammation of the CNS in the past then as you get older 45+ then you can get age related neurodegeneration in the area of previous inflammation. He told me that he had another patient in a similar position to me who had tried to hang himself 20 years previously. Another neuro I saw thinks possible progressive MS but cant give a definite DX as LP was negative and brain scan clear.
So past injury can cause neurodegeneration later in life that may look like MS and some people may get that DX whether or not its right or not.
