Body throbbing

had a root canal, and gum therapy due to heat sensitivity. before giving me the i guess it was a anesthetic they say now but before he said with heat sensitivity there is a medicine we put in the gums and its important that its heat sensitiv because if not it may be viewed as a toxin by your body. i was also giving amoxicillian at that time. two weeks later i went back to the dentist i have throbbing in the area and throbbing in my body, some good days, some bad days. they reclean the area and go back into the tooth, given another antibiotic azithromycin(sp?) Swelling goes away from my left eye, my left ear is great not all tight and ringy, i feel great on this a week or so i slowly am getting this throbbing back in my body not to bad, i go to the dentist again told him good days and bad days, they put a temporary on, it was silver. during this time slowly i am throbbing after a week or so my left eye above the #14 tooth which was worked on, swells again and  throbbing  peaks and then reverses and now my eye feels chapped and burny in the area around my eyes and upper jaw, the corner of my mouth on that side is all chapped and skins rough. Basically everything on my left side is wierded out. then the two days until my dental visit, this improves somewhat. I told the dentist he put the crown on, after he put on the crown on when the assistant was flossing it the crown pops off, she puts more cement on and puts it back in, i feel great for a few days, out of floss, so i get some when i went to floss it felt like i was going to pop the crown off..cement comes off and now the throbbing begins again! i go to kaiser regular docter my blood pressure is through the roof and i am retaining water and swelling. they give me triamterene/hydrochlorothia, for my blood pressure and run some tests which i will be getting tommorow. two days after taking that i got one of the sideeffects which was diarrhea oh well. but only once and there was a wierd blue grey substance in the water that would not mix with the water only floating kinda bubbly?? doesn't happen again and i feel great except for throbbing in the upper jaw only there not in my body anymore. I go to the dentist i am asking for the name of the anesthetic for the gum thereapy because what if my body views it as a toxin? and also because my kaiser docter wanted to know everything that had gone in my body recently. they think it is that i am allergic metal which my grandma and my mom can't wear anything but gold in their ears and no metals, so maybe this is, but they wont give me the name of the anesthetics because they dont think that it is. these same dentist tryed saying my first temporary wasn't metal, which it was and proved to them it was. so they take the crown off my tooth because i was lined with metal, and they make me a new temporary with out metal which was white, wear the other was silvery and i was like those different and they they realized oh yeah. so they tell me to go get a metal test at the docters. i feel great that day which was yesterday, and then towards evening kinda gittery, i didn't sleep good last night and today have been throbby the blood pressure stuff doesn't all of a sudden? or is it the anesthetic? or recovering from the metal? All i know is i wasn't throbbing before, and the dentist kept asking questions of the heat sensitivity and told me the if my body doesn't need it, it may be a toxin in my body and my body can't prossess it or i dont want my body to process it because of kidney stuff, but we dont want to get into that. they called it there gum thereapy medicine, now that they call an anesthetic. i dont know what is going on all i know is i feel like i am getting jerked around and my health is suffering from it.........
