Confusing: Your post is a bit confusing grammatically, but i think you're asking if a little pain after an extraction is normal, and the answer is yes. In any event, any discomfort following a surgical dental procedure should be followed up with the surgeon. Feel better soon...

Surgery?: What kind? Have you discussed your symptoms with your surgeon? If not, please do so as post-operative care is part of your surgical procedure. Some discomfort is to be expected after surgery, diminishing with time. If pain is decreasing, you have no fever/chills, there is no bleeding, and (if mouth surgery) you don't have a bad taste, your probably OK. But check in with Surgeon to be sure.
