Hello! So this has been bugging me for a while. I don't know what it could be, but these are all my symptoms. Years ago I used to get heart palpitations, tingling in my feet, burning toes, fingers, severe anxiety sometimes without an apparent cause. so I got vitamin d3 supplements, and b12 suppements. After the b12 supplements, all these symptoms were gone. I felt a lot better. Recently my lactose intolerance has worsened too. Could it be celiac disease? I'm in my late teens btw. i don't have any other symptoms, other than constipation. i never feel urge to poop. only a mild pressure.
For constipation, consider some laxatives. Drink more water.
Lactose intolerance is when you don’t digest dairy products well, and Celiac disease means your body is not digesting the gluten properly.
