Need to extract 2 root canal teeth by a regular dentist

Hi everyone,

I wanted to get advise on my issue. About 4 years ago, I went to dentist my brother use to go (by recommendation) to do some dental work (fillings). I had 2 black spots on the side on my 2 side teeth. Well, he hit root on one (as he said to me) and said I would need a root canal done. Long story short, I didn't really follow up with him or anyone after that, because I had no pain, and hoped it would heal itself. It turned out 4 year later when I finally had pain that he actually damaged not one but both
teeth nerves. So recently I had 2 root canals done at once, even though I don't think I really needed immediately to do anything with the second one (if anything at all).

After I had them done, when I got home I developed very strange and scary symptoms (heart palpitations, elevated heart rate, which is so bad, I can't sleep at night and it actually also gives me anxiety as well, because I really don't know what to do. I went many times to emergency, they checked my heart saying that your EKG is normal and nothing wrong with your heart. I called that office to give me the list of materials used on me, as I am thinking I am having some allergy or adverse reaction to something in those root canals. They don't want to give everything was used, saying will call you back etc. which is so frustrating! I am not sure what to do next, everything is so expensive today. I am thinking to extract both teeth with a regular dentist and tell them to remove periodontal ligaments and well as to clean the cavitations. I had them done about 3 weeks ago. Do you think it would be safe to do that if I wanted to with that?

Thank you for your help and suggestions!!!
