Similar symptoms for PF are in the Gout section. The elimination diet includes no alcohol, shellfish, organ meats, meat, yeast, fats, excessive calories and sugars, and to limit spinach, asparagus, fish, poultry and mushrooms.
I have also learned that high protein intake can lead to shortage of B6 which is linked to Carpel Tunnel Syndrome (similar to what I have of Tarsel Tunnel Syndrome and PF).
I've just wondered anyone's experiences with any of these? Certainly, it is worth a try and it will help with the weight factor, too.
