From your history I could gather the fact that you have a wound infection
after getting your tooth extracted.When you went to the hospital you were connected to a pulse oximeter
which showed that you had a low respiratory rate
and a low heart rate
.Usually in fevers your heart rate increases unless you are taking medicines like beta blockers which reduce your heart rate.If your chest pain
persists and you are a diabetic it is better for you that you get admitted .Get a basic blood work up done.you can also have an ecg taken which will give you an idea if the chest pain is related in any way to your heart.
