Hi, I went for a root canal about two and a half weeks ago, I had a previous issue with this dentist who made a mistake on a root canal I had before. I had no intention of going back to him, but the oher dentist in the office wasn't available and the tooth was in desperate need of fixing. So, a little over two weeks ago, I went in for my root canal, everything was going well until close to the end. He was drilling and "accidentally" drilled into my sinus cavity... It was horrible, and at the time he was injecting a syringe full of a bleach solution to cleanse the root, which was suppse to come back out... Well the solution stayed in me, forcing blood and mucus through my nose and into the nitrous mask. It was burning horribly and my eyes were watering. He closed the tooth without finishing the root canal telling me I would have to come back in 6 days to finish it. He sat me up in the chair, took an Xray and showed me where he drilled through, then sent me off with antibiotics. My nose was bleeding constatnly which I assumed was normal. I took the monday off work as I work heavy construction and didn't think it would be wise. I went to work the tuesday and had to go to the emergency room that night, I was in such horrible pain, I had a severe migraine, my nose bled all day, and I spit up blood clots. They ordered a CT Scan for the following saturday. I took the wednesday off work then worked half a day the thursday, unable to handle the whole day because of the same symptoms. Finally about 5days after I got the CT scan I got the results, they read that I have a "sinus disease" and that it appears my sinuses aren't draining, although the doctor couldn't explain why I was having migraines. He gave me T3s for my pain and more antibiotics for the infection. I got reffered to a ENT specialist and just had my appointment today. The specialist said that it would benefit me for her to go in and clean out the sinuses through surgery. She also said that judging by the CT Scan she can't see why I'm having migrains, and that it is not becasue of the sinuses. She said it is possible that he cold have hit a nerve but that was all she said. I have never even had a headache before in my life (other than alcohol related ones which is scarcely seldom) and this is absolutely unbareable. This is my third week off work, I can't even bend down to pet my dog without getting a migraine and blood leaking out of my nose. I have always been an exceptionally healthy guy, never had a sinus problem before either... Now I don't know what to do... Sneezing, coughing, laughing, going up stairs, bending over all causes incredible pain. Also, when I read I find my vision is off in the eye above where the rootcanal was preformed. I have several nose bleeds a day, and when they occur I can taste and smell the bleach solution that was put in me. I wake up about three times a night from my migraines... I am very concerned about this, especially about the pain and throbbing in my head and behind my eye. Also, when I bend over it feels as though my eye is bulging. Has anyone experinced this before? Or something similar? Is this right? Nobody seems to be able to help me or tell me everything. I have not finished the root canal yet, and am obviously doing it with a different dentist. I plan to see another specialist out of town but am seriously concerned. Any advice would be immensely helpful... Thanks!
