I am wondering about the negative effects of root canals. I had mine done in April and since I have just been crap. I first developed what you would call carpal tunnel. Then bad constipation which since has gotten a little better. I also have had other symptoms that have gone away. But the one I'm worried about right now is my nerves. I got a very sensitive spot on my right arm. My skin in one spot is very sensitive. I also have pain in my leg, like a nerve or something.Also pain in lower left and right intestines. I still have carpal tunnel. My question is could these things be related to the root canal. I think they are but don't want to get it removed if I don't need to or whatever.
