Dental advice

I’ll start by saying I have called my dentist and they were no help, they told me they couldn’t look at it in 02/22. I had a filling on Thursday 01/26 and it’s been 4 days, my tooth has not stopped hurting since I’ve had the filling. I have a horrible headache because of it and I don’t know what to do. I’ve taken ibuprofen and it didn’t help, could it be an infection?
