Depending what i eat will determine how bad my carpal tunnel gets at night time?

Avoid nightshades: Avoid foods in the nightshade family as they contribute to inflammation. They include peppers, eggplant, cayenne pepper, paprika, pimentos, potatoes and tomatoes. Here is a link for others http://www.Thepaleomom.Com/2013/08/what-are-nightshades.Html.

Fluid retention: Any food that causes you to retain fluid, hence increasing edema in the extremities, will exacerbate your carpal tunnel by increasing the pressure in the canal. This causes greater compression of the median nerve worsening your symptoms.
