Your self medication is ineffective. Post-surgical care is the province of your Surgeon. There are procedures to address dry socket that will give you substantial relief. Immediately call the General Dentist or Oral Surgeon who did your extractions. Instructions to do so are probably on the written instructions provided to you at time of surgery.
