I am going to explain what CRP and ESR
is and then what conditions it is raised in. CRP stands for C reactive protein
. It is raised in conditions that cause chronic inflammation. The inflammation cause the CRP to be raised.
ESR stand for erythrocyte sedimentation rate
. It is also used for inflammation in the body. So, basically all this means is that your son has some inflammation somewhere in the body.
Since you are meeting a neurologist
, I suspect that he has an autoimmune disorder affecting the spine. This could be something like Guillane Barre syndrome. This can also cause the cramps that you have described. I hope this helps you.
