It sounds by your description that the tooth has a pulpitis in which the dental pulp inside the tooth is inflammed and causing you pain. With the swollen lymph nodes and other symptoms, you may be getting an abscess which the antibiotics help to resolve but it not a long term solution. You should go to a dentist (whether or not you decide to go to the same dentist is up to you) and get it checked out. It may need a root canal or it may need to be pulled.
Oh and yes, one more thing - I wasn't having symptoms at the time, but 3 months ago my ENT put an endoscope into my sinuses and everything looked normal.
Yet something else I remembered, I have also noticed that when I walk up stairs or first stand up, or exercise the pain sometimes throbs along with my heartbeat in the tooth area. In face, I think it flared up when I was lifting weights just over a week ago.
Not to keep rambling, but just an update. I stopped taking the Amoxil yesterday because I don't like the side effects of lightheadedness. Right now, it doesn't hurt to bite down, but the bone under my gums above the tooth is sore to the touch, and it feels like I have a lot of soft tissue puffiness in my jaw and inside my mouth right now, plus my lymph nodes are still swollen and hurting. I've been using mouthwash vigorously since yesterday, I think that's what I did differently last time. I don't know if it's working yet or not, but it's not all gone away by any stretch and I figure it'll just flare back up anyway. Do I need to get that tooth pulled?
Hi, thanks for the response. I went to the dentist today who did the work before, he took new X-rays and saw nothing abnormal (like before). He tapped on my tooth some with his mirror, and then blamed my sinuses. He gave me a different anti biotic, but I went to my ENT also after I left there and he did an endoscope into my sinuses and said they look clear. He could feel my swollen lymph nodes. He, too, suggested different anti biotics, but here is what I can't figure out... why? Something is obviously causing this, and it's not my sinuses. I think obviosly the Amoxil calmed down the pain a great deal for me especially in the tooth/sinus area, but the bone in my gum is still painful and my glands are still swollen, plus I think it will just come back like it did before. Do you perhaps have something else you could add?
Thanks for your time, I really do appreciate it
You may want to see an endodontist to see what they say. An endodontist is a root canal specialist and they may see the need for a root canal which is where I'm thinking is the necessary treatment.
