If you have increasing pain as a result of low carb diet, a few ideas come to mind.

1. Are you checking ketones along w/blood sugars. *very important*

2. Low carb diet if combined w/ thyroid disorder is sometimes can increase pain.

3. Is it possible that you're sensitive/intolerant to *some food* that was increased in your diet as the carbs disappeared.

4. If you love spices, tomato, eggplant, or are using a lot of nonorganic soy, ck. out possible nightshade intolerance. Potato is also on the nightshade list, however it's off of most low-carb diets.

Best wishes.
