I have had surgeries, tooth pulled, tooth pain and always had to beg, plead and argue with these people that I have to trust with my life. It absolutely infuriates me. In fact, finding any Medical Professional who is "FAIR" about prescribing for pain is such a rarity and I also can speak for friends and relatives. I have NEVER heard of anyone NOT needing pain medication for a root canal. That's absurd! I would call and keep calling that Dentist and explain the pain I was in, what I have taken, how much I took of it and that I NEED something stronger. I don't know what the story is about the withdrawal situation but, to me, that's besides the point at this moment in time and it just so happens that if you were to get any help from this Dentist it would just be killing two birds with one stone,,for now. I hope by now you are feeling a little better and I would start looking for another Dentist for the next time. Good Luck to you,,, with everything.
