If I have a dangerous infection, would any of my symptoms improve with Amoxicillin?
So, long story. I had a root canal tooth pulled last Wednesday. They initially thought it may be infected, but were less sure after seeing the second X-ray. They pulled it anyway, and it was a traumatic pull (difficult, took nearly 90 minutes to complete).
I was okay after that... until I woke up at 3AM on Thursday with shivers (in spite of being warm to the touch) and light-headedness. Later that day, I called the dentist and asked his advice. He seemed to disregard it, but acknowledged there may be an infection. He prescribed me Amoxicillin (and Tylenol-3). I went home and basically spent the last two days lying in bed, taking my medicine as prescribed, and sleeping when I could. Some of my symptoms (temperature shifts, flop sweat, some of the light-headedness) improved. I threw up a couple times in the first 24 hours of the antibiotics, but haven't been nauseous since.
Except my symptoms are still fluctuating (or in the case of my faster than usual heart-beat, haven't changed), and now I'm sore in some areas - most worryingly, a very faint pain in my neck. My biggest fear is Bacterial Meningitis. Although I expect I would be much sicker after 4 days than I am (I'm not exactly rushing to the hospital), I guess my question is: Would standard Amoxicillin improve ANY of my symptoms if this were serious? Should I be more or less concerned that I'm improving, but not consistently?
