It’s pretty normal to have pain 2-3 weeks after the extraction of teeth and as Jerome Tsang stated gentle irrigation can be fine to proceed. However, get consulted to your dentist as there may be many potential risks of wisdom tooth extraction and it must be reviewed with your dentist.
At one week, there should be sufficient time for the blood clot to solidify in the socket. Gently irrigating it should be fine.
Depending on how difficult the extractions are, its possible to experience pain for a bit of time. As long as its getting better and gradually healing, I would monitor the situation. You may want to call and ask for your particular case though
